The system administrator can create one or several mailing lists. Users
from the same or any other mail system can subscribe to these mailing lists
using the Web interface or by sending E-mail. They can post messages on
mailing lists by sending E-mail to the list addresses, and posted messages
are delivered to all subscribers. All posted messages are stored in the
mailing list Mailbox that serves as an archive.
If a user subscribes in the FEED mode, all posted messages are redirected
to that user immediately after they are received by the LIST module.
When a user subscribes in the DIGEST mode, the user starts to receive
list digests: a multi-part messages generated with the LIST module for each
mailing list. Each digest message contains all messages posted on the list
since the last digest was generated, prefixed with an index of these messages.
When a user subscribes in the INDEX mode, the user starts to receive
messages containing the indexes of newly posted messages. If the user wants
to read some of the posted messages, they can use a Web browser to access
the mailing list archive.
Use the WebAdmin Interface to configure the LIST module.
Open the Mail pages in the Settings realm, then open the LIST page.
Log
Use the Log setting to specify what kind of information the LIST module
should put in the Server Log. Usually you should use the Major
(message processing reports) level. But when you experience problems with
the LIST module, you may want to set the Log Level setting to Low-Level
or All Info: in these cases more details will be recorded in the
System Log. When the problem is solved, set the Log Level setting to its
regular value, otherwise your System Log files will grow in size very quickly.
The LIST module records in the System Log are marked with the LIST tag.
Processors
When you specify a non-zero value for the Processors setting,
the LIST module starts to process queued messages directed to mailing lists,
starts to generate digests, and starts to clean the mailing list archives. The
module can use several simultaneous processors (threads) to process several
mailing lists at the same time. If you have more than 50 mailing lists,
or if you have many lists with extremely large (10,000+) subscriber lists,
you should allow the module to use more than 1 processor.
This table shows all mailing lists created. By following the links in
the table, you can open an individual list setup page,
the Domain Settings page for the list Domain,
or the Account Settings page for the mailing list owner.
Each Mailing List is created inside the Main or one of the secondary
Domains, and each Mailing List belongs to its owner - an Account in the same Domain.
To create a Mailing List, create an Account or choose an existing one - the List owner Account.
Use the WebAdmin Interface to open the Account Settings page:
To create a mailing list, type the list name and click the Create Mailing List button.
If you are a Domain Administrator, you should have the Can Create Mailing Lists
Access Right to create Mailing Lists in your Domain.
The Server checks that there is no Account or other Object with the same name in this Domain, and creates a new Mailing List.
Several Mailboxes are created in the List owner Account:
listname
this Mailbox is the Mailing List archive: it contains the messages posted to this Mailing List
listname/requests
this Mailbox contains the messages with subscription requests.
listname/reports
this Mailbox contains bounce and other DSN (Delivery Status Notification)
messages generated for the messages distributed via this Mailing List.
listname/approval
this Mailbox contains postings that require the list owner approval (moderated postings).
To post these messages, the Mailing List owner should redirect them back to the Mailing List using an authenticated submit method:
a MAPI or XIMSS client,
the CommuniGate Pro WebUser Interface,
the XTND XMIT POP3 method, a local "mail" command,
the PIPE module, etc.
To configure a Mailing List, open the Mailing List Settings page. You
should select a link to the Settings page either from the list of all mailing
lists located in the LIST module Settings page, or from the list owner
Account Settings page.
You should have the All Domains Server Administrator access right or
the Domain Administrator access right
in order to open the Mailing List Settings pages via the WebAdmin Interface.
In order to modify a Mailing List settings or subscriber lists, the Domain Administrator
should have the CanAccessLists access right.
The list owners can access the Mailing List settings pages using the WebUser
Interface with their Accounts. The WebUser session page listing Mailboxes and Mailbox folders also provides
links to the Account Mailing Lists pages.
Log
Use the Log setting to specify what kind of information about this
mailing list should be put in the Server Log. Usually you should use the
Major (message posting, subscription, digest, and clean-up operations)
level. But when you experience problems with this particular mailing list,
you may want to set the list Log Level setting to Low-Level or
All Info: in this case more details will be recorded in the System
Log. When the problem is solved, set the Log Level setting to its regular
value, otherwise your System Log files will grow in size very quickly.
The mailing list records placed in the System Log are marked with the List(listname)
tag.
Only the system administrator can change the mailing list Log setting.
Description
Use the Description setting to specify the full name of the list. It
will be used as a "comment" in the list E-mail address as the
Real Name setting is used in account E-mail addresses.
Preferred Character Set
This option specifies how the List module should handle non-ASCII texts.
It is used when displaying list messages via the Web interface: messages in the list
can be composed using different character sets, and to display them all on one page,
the module should know which character set is preferred.
Digesting and Archiving
Posted messages can be stored in a Mailbox created in the list owner
Account. Such a Mailbox is used to collect messages for message digests.
If messages are not removed from that Mailbox after a digest is created,
this Mailbox can be used as a mailing list archive.
Enabled
All posted messages are stored in the
owner Account Mailbox. Use the link next to the pop-up menu to open the
Digesting and Archiving Settings page.
Disabled
The posted messages are not stored in the owner Account Mailbox,
archiving and digesting options are disabled.
All digest and index-mode subscribers are processed as feed-mode subscribers.
All new attempts to subscribe to the mailing list in the digest or index mode are rejected.
Verify Owner
When the LIST module receives an E-mail message, it checks if the message is
sent by the List Owner. First, the message Return-Path is compared to the list
owner E-mail address. The Return-Path should be ownerName@listdomain,
where the ownerName is the owner Account name (not one of its aliases), and the listdomain
is the list and owner Account Domain name (not one of its Domain aliases).
The Verify Owner setting specifies the additional checks to be made:
Return-Path
When this option is selected, no additional check is made.
IP Addresses
When this option is selected, the LIST module checks that the message has been
submitted either using one of the authenticating methods (see below), or via SMTP, from
a computer with an IP address included into the Client IP Addresses list.
Authentication
When this option is selected, the LIST module checks that the message has been
submitted using one of the authenticating methods:
The Settings page contains a set of options, settings, and text areas
that controls the subscription, postings, message distribution, and bounce processing.
See the sections below for the details.
To rename a mailing list, open that list Settings page via the System Administrator Web interface (see above).
You should have the All Domains Server Administrator access right or
the Domain Administrator access right
in order to open the Mailing List Settings pages.
Enter the new name for the list in the Mailing List Settings page, and
click the Rename button. The Server checks if there is no Account or Mailing
List with the new name in the same Domain and renames the mailing list.
Then the Mailing List Settings page is reopened.
To remove a mailing list, open that list Settings page via the System
Administrator Web interface (see above).
Click the Remove List button. A confirmation page appears. If you click
the Remove button on the confirmation page, the list is removed, the
files with the list subscribers and list settings are deleted,
and the mailing list Mailboxes are removed from the list owner Account.
Several Mailing list settings specify texts to be sent to the subscribers -
message subjects, message headers and trailers, confirmation requests, etc. A specified
text can contain special symbol combinations to be substituted with actual
data before the text is inserted into a message.
The following symbol combinations can be used:
Where
Combination
Substituted with
All Texts
^N
the listname string
^D
the domain string
^E
the Description setting
Digest Subject, Header, Trailer
^X
the sequence number of the current digest
Feed Subject Prefix, Header, Trailer
^B
the sequence number of the current message
^C
the original message 'From' address
If there is a number after a special symbol combination (as in ^N80), the number specifies the maximum length of the substitution string.
If a substitution is longer than specified, its last symbols are cut off.
If there is a number after a special string combination, and the number
starts with 0, as in ^N040, the number specifies the length of the substitution string.
If a substitution string is longer than specified,
its last symbols are cut off, and if a string is shorter than specified,
space symbols are added to the beginning of the string.
If the number starts with two 0 symbols, the 0 symbols are used instead of spaces.
Each mailing list is a list of subscribers, i.e. a list of E-mail addresses
receiving messages posted on the mailing list.
In order to subscribe, unsubscribe, and change their subscription mode via
E-mail, users of the listname@domain mailing list should
send any message to the following addresses:
Send to address:
New user
Existing subscriber
listname-on@domain or listname-subscribe@domain
to subscribe to the list in the default mode
to confirm the current subscription mode
listname-feed@domain
to subscribe to the list in the FEED mode
to change the subscription mode to FEED
listname-digest@domain
to subscribe to the list in the DIGEST mode
to change the subscription mode to DIGEST
listname-index@domain
to subscribe to the list in the INDEX mode
to change the subscription mode to INDEX
listname-null@domain
to subscribe to the list in the NULL mode
to change the subscription mode to NULL
listname-off@domain or listname-unsubscribe@domain
to unsubscribe from the list
listname-confirm@domain
to get the confirmation ID; this ID can be used as the password for other
subscription operations and for list archive browsing
When subscription request messages are sent to these addresses, the message From: header fields are used as requesters E-mail addresses.
You can specify who can subscribe to the mailing list, and how they should subscribe.
Subscribe
nobody
users cannot subscribe to this mailing list and/or
change the subscription mode by themselves. Only the system administrator and the
list owner can do these operations. Users still can unsubscribe by themselves.
this domain only
only users from the mailing list Domain can subscribe.
locals Only
only users registered with this Server can subscribe.
anybody
any user on any system can subscribe to this list.
moderated
all subscription requests will be stored in the listname/requests
Mailbox (see below) and should be approved by the list owner.
The List owner should redirect these requests
to the listname-on, listname-feed and other addresses to subscribe
new users and to let them change the subscription mode. Users still can unsubscribe
by themselves. When user requests are stored in the listname/requests
Mailbox for approval, they are "flagged" (get the Flag marker).
Save Requests
This setting specifies which subscription requests (i.e. messages sent
to the listname-on, listname-off and other addresses listed
above) should be stored in the listname/requests
Mailbox in the list owner Account. Messages stored in this Mailbox can
be examined if some user reports problems when trying to subscribe to,
unsubscribe from, or change the subscription mode to this list.
You can specify if none, all, only the accepted, or only the rejected request messages should
be stored in the listname/requests Mailbox.
Requests waiting for the list owner approval are always stored in the listname/requests
Mailbox.
All stored request messages get the X-List-Report additional header field . This
field contains the list manager report (Delivery Status Notification message). It is recommended
that the List owners configure their mailer applications so they display the X-List-Report fields.
Default Mode
When a new user sends a subscription request in to the listname-on@domain
or listname-subscribe@domain address, i.e. when the subscription
mode is not specified, the mode specified with the Default Mode setting
is used.
Each list user (E-mail address) is subscribed in one of the following modes:
FEED
In this mode, the subscriber receives list messages as they are posted. See the
FEED Mode Distribution section for more details.
DIGEST
In this mode, the subscriber periodically receives digest messages. A digest
message starts with the Table Of Content - the list of the messages posted, followed by
the posted messages themselves. See the DIGEST/INDEX Mode Distribution
section for more details.
INDEX
In this mode, the subscriber periodically receives index messages. An index
message is the same as the digest Table Of Content, but it does not contain the posted messages
themselves. INDEX subscribers can see if they are interested in any posted messages, and use
the Web interface to read those messages in the mailing list archive.
See the DIGEST/INDEX Mode Distribution section for more details.
NULL
In this mode, the subscriber does not receive any messages from the list. This mode
can be used by the "posters" - the list users that only post messages on the list.
BANNED
The "banned" users do not receive messages from the list, and they cannot change
their subscription mode themselves.
You can use this method to make it impossible for certain users to subscribe to your
mailing lists, though usually the more generic anti-spam and other system-wide protection
methods should be used.
There are several very common problems with most of publicly available mailing lists:
subscription messages are sent from incorrect addresses, those incorrect
addresses are inserted into the subscribers list, and mailing list messages
are repeatedly sent to those incorrect or unused addresses.
list abusers (such as spammers) subscribe nonexistent E-mail addresses
just to allow themselves to post on the lists that accept posts from subscribers
only.
using easily forged message headers, some persons can subscribe and
unsubscribe another person E-mail addresses.
These and some other problems can be solved using confirmation requests.
Request Confirmations
When this option is selected, the List manager does not fulfill subscription
requests immediately. Instead, a confirmation request message is composed
and sent to the address that is about to be included or excluded from the
subscribers list. The confirmation request contains a unique identifier
(Confirmation ID) in its Subject field. When the user receives such a confirmation request,
they can simply use the mailer Reply command to confirm the requested operation.
Confirmation Message
These text settings allow you to specify the subject and the body of confirmation request messages
the module sends to the subscribers. In addition to generic "symbol combinations",
these service texts can also contain the following combinations:
Combination
Substituted with
^O
the requested operation
^P
unsubscribe for the unsubscribe operation, subscribe for the subscribe operation,
and subscribe(operation) for other operations
To post a message on the mailing list, the author should send it to the listname@domain address.
Accept Postings
This setting specifies who can post messages on this mailing list:
from owner only
Only messages submitted by the list owner (using any authenticated method) will be posted
moderated
Messages from everybody but the list owner are redirected to the list owner for approval; if the list owner
redirects a message back to the list, the message is posted.
Note: this mode can be used to change the list posting policy when the list owner wants to postpone all postings.
If you use the from subscribers mode, the New Subscribers setting (see below) provides more advanced moderation options.
from subscribers
Messages from the list subscribers are accepted for posting; some messages
can be moderated (see below).
moderate guests
Messages from the list subscribers are accepted for posting; some messages
can be moderated (see below). Messages from addresses that are not subscribed are moderated.
from anybody
Messages from any address are accepted for posting.
New Subscribers
This setting is effective only if the Accept Postings setting is
set to from subscribers. When a user subscribes and starts to
post messages, the messages are stored in the list owner Mailbox waiting
for approval. After the specified number of messages is approved and
posted, all messages sent by this user are posted on the list directly,
without the list owner approval.
Note: this is a very effective way to enforce the list policies and to protect the mailing list from "spamming". If you set this option to Moderate All, then all messages from new subscribers
will be stored for approval (the LIST module will not update the posted messages counter).
If you set this option to Prohibited new subscribers won't be able to post
on the list (their postings will be rejected).
If you set this option to Special, new subscribers will be able to post
auto-generated messages. This is useful if you want to subscribe this mailing list to other mailing lists.
Note: when an auto-generated message should be posted on the list, and the message
is not a message generated by the list owner, the message Sender address (if exists) is used instead of the From address.
If that address is subscribed to the list, and the subscriber posting mode is set to Special, the message is posted.
You can open the subscribers list and change this setting for individual subscribers.
You may want to change this setting to Unmoderated for some users, letting only those
users post messages on the list, while posting from all other users (and new users) will be
either stored for approval or rejected.
Allowed Format
This setting specifies the allowed MIME format for postings.
plain text only
only messages in the text/plain format can be posted
text only
only messages in the text (text/plain, text/html, etc.) formats can be posted
text alternative
only messages in the text format or multipart/alternative messages
that contain a part in the text format can be posted (for example, a message can contain a text/html variant part and
the same text as a image/gif variant part)
anything
messages in any MIME format can be posted
The list owner can always post messages in any format.
Maximum Size
This setting restricts the size of messages that can be posted on
this mailing list. The list owner can always post messages of any size.
When this option is selected, the Subject fields of all postings are
checked. If the Subject is a "reply prefix" (such as Re:, Re>,
etc.) followed by this list Digest String (see below),
the message is rejected.
Prohibit Non-matched Character Set
When this option is selected, the character set used to compose the posting is checked.
If the character set is explicitly specified, and it does not match the Preferred Character Set for this
list, the message is rejected.
Service Fields
Use this option to specify the message header fields to be added to all distributed messages (feed, digest and index).
If this option value starts with the asterisk (*) symbol, the module automatically generates the
List-ID, List-Unsubscribe, Precedence and (if list browsing is enabled) List-Archive fields.
Otherwise, the specified fields are added. The following symbol combinations can be used in this field:
Combination
Substituted with
^N
the listname string
^D
the domain string
^P
the first HTTP User module port
^R
the http or the https string, depending on the type of the first HTTP User module port
Compose 'From' Address as:
This setting specifies how the 'From' addresses of the senders are modified in posted messages.
Author Name and Address
The original Author name (the comment part) and address are used.
Author Name and List Address
The Author name is used but the address is replaced with the List address. Use this option to make List messages to be compatible with DMARC.
Author Name with Address and List Address
Same as above but also the Author address is inserted into the comment part.
When a posted message is being sent to subscribers, the original message
header is modified. Usually, only the From, Date, Message-ID, and Subject
fields are copied from the original message.
You can specify additional header fields to be copied from original
postings to the messages sent to subscribers - directly or as parts of digests.
Use these fields to specify the names of additional RFC822 header fields to be copied from the original postings to the distributed messages.
If you want to remove a name, enter an empty string into the name field.
If you want to copy all header fields, enter the asterisk (*) symbol into the first field.
If you want to copy the Message-ID for the messages distributed using the "feed" mode, include the Message-ID field name.
If the To And Cc option is set to:
remove - the original To and Cc fields are not copied; the Mailing List address is added as the To field;
keep - the original To and Cc are copied;
copy as Cc - the original To and Cc fields are copied as Cc fields; the Mailing List address is added as the To field.
Incorrect and expired E-mail addresses create the most annoying problems
for mailing list administrators. The CommuniGate Pro LIST module automates
processing of incorrect, expired, and temporarily unavailable addresses.
All messages sent to subscribers (in all modes) have message envelope
information that routes all error reports back to the LIST module. When
a report is received, the LIST module:
stores the report in the listname/reports Mailbox in the owner Account (optional);
parses the report text;
if the report has a correct delivery-report (RFC1892/RFC894) structure, processes all records in the report.
Most of the problems can be detected immediately when sending a list
message from the CommuniGate Pro Server, so most of the error reports are
generated locally, on the same CommuniGate Pro server. The CommuniGate
Pro server generates reports in the proper format, so most of the delivery
problems are handled automatically.
If a list message has been sent to a remote site without a problem,
but then that remote site fails to deliver the message to the recipient,
the delivery report is generated on that remote site. Most of the modern
mail servers generate delivery reports in the correct format, so in this
case many problems are handled automatically, too.
And, finally, it is still possible to receive unformatted delivery reports
from other sites. The LIST module can store those unformatted reports in
the listname/reports Mailbox, so the list owner can process them
manually.
Each record in the delivery report contains information about one E-mail
address, and indicates if the original message was or was not delivered
to that address. It can also specify if the delivery problem is fatal (as
when account is removed from the system), or if it is a non-fatal, temporary
problem (as when a remote site is down or when the account disk space quota
is exceeded).
If a non-fatal report is received, the E-mail address in question is
suspended, and no list messages are sent to that address, and all additional
error reports about that address are ignored. When the LIST module performs
periodic list clean-ups, it sends a warning message to all suspended addresses.
The warning message notifies that user that some list messages have not been
delivered to the user address, and it also asks the user to confirm subscription
(by replying to the warning message).
There are two ways to specify the suspension period:
An address can be suspended for a fixed period of time. When that period
ends, the LIST module resumes sending list messages to this address.
This can result in new bounces which will increment the bounce counter, and
the address is unsubscribed after the bounce counter exceeds the specified limit.
The warning messages are sent to the failed address after the
suspension is over, too - till the user confirms the subscription by replying to
the warning message.
An address can be suspended till the user confirms subscription by replying
to the warning message. If no confirmation is received during the specified
period of time, the address is unsubscribed.
When a user confirms the subscription by replying to the warning message,
the suspension period ends, and the bounce counter
associated with the user E-mail address is cleared.
suspend subscription for
If this option is selected, it specifies for how long a subscriber should be
suspended if the system receives a non-fatal problem report about the subscriber's
E-mail address.
The unsubscribe after option specifies the number of unconfirmed suspension
periods after which the user is unsubscribed.
suspend till confirmation
If this option is selected, a non-fatal error report suspends the address
till the subscriber sends a confirmation message.
The unsubscribe after option specifies the time period to wait for
a confirmation message.
Process a Fatal Bounce as
This setting specifies how the system should process fatal problem
reports: as non-fatal, as several non-fatal, or as a fatal problem. If
you specify that the system should unsubscribe a user after receiving 10
non-fatal problem reports about the user address, and you specify that
a fatal problem report should be processed as 5 non-fatal reports, this will tell the system
to unsubscribe the user after 2 fatal reports. If you specify that a fatal
problem report should be processed as fatal, the system will unsubscribe
a user immediately upon receiving a fatal problem report.
Notify Owner When Unsubscribing
If this option is selected, an E-mail message is sent to the List Owner
every time an address is unsubscribed because of mail bouncing.
Cleanup List every
This setting specifies how often the system should scan the subscription
list. When scanning the list, the system:
sends warning messages to the subscribers with non-zero bounce counter;
removes subscribers who sent subscription requests more than 2 days
ago and who have not confirmed the subscription requests;
removes unsubscribed addresses from the list.
Bounce Reports to Save
This setting specifies which delivery reports should be saved in the
listname/reports Mailbox in the list owner Account.
If you specify unprocessed, only the messages that the LIST module
fails to parse and process are stored in that Mailbox.
Warning Message
These text settings specify the subject and the text of a warning message
that is sent to subscribers when their subscription is suspended. In addition
to generic "symbol combinations", this service text can contain
the following combinations:
After a message is posted, it is distributed to all users subscribed in the FEED mode.
The To header field of a distributed message contains the mailing
list address. The From, Date, and Message-ID
fields (and specified additional fields)
are copied from the original posting.
The body of the distributed message is a copy of the original message
body. If the original message was not in the MIME format, or if it was
in the MIME text/plain or multipart/mixed format (the most common formats),
the FEED Mode Header text is inserted before and the FEED Mode Trailer
text is inserted after the body of the original posting.
Subject Prefix
This setting specifies the string that is inserted into the beginning
of the Subject field of all messages distributed in the FEED mode.
When a message is distributed, the system checks the Subject field. If
the subject prefix found after the reply prefix (Re:, Re>, etc.), then
the subject prefix is deleted.
The Subject Prefix string can contain special symbol combinations.
insert after Reply Prefix
Select this option to insert the Subject Prefix after the Reply prefix
(this helps client mailers to group related messages into discussion threads).
Sample:
the Subject Prefix setting
[R&D]
a posted message
Subject: test
the distributed message
Subject: [R&D] test
the posted reply
Subject: Re: [R&D] test
the distributed reply (insert after Reply Prefix is not selected)
Subject: [R&D] Re: test
the distributed reply (insert after Reply Prefix is selected)
Subject: Re: [R&D] test
the composed digest
1) test 2) Re: test
Direct Replies
If the to List option is selected, the Reply-To header field
with the E-mail address of the list is added to all distributed messages.
As a result, when subscribers answer to distributed messages, their replies
are directed to the mailing list by default.
If the to Sender option is selected, the Reply-To header is
inserted with the From address of the message author (sender).
Header
This setting specifies the text to be included in the beginning of
messages distributed in the FEED mode.
The Header string can contain special symbol combinations.
Trailer
This setting specifies the text to be included at the end of messages
distributed in the FEED mode.
The Trailer string can contain special symbol combinations.
Posted messages can be stored in a Mailbox created in the list owner
Account. Such a Mailbox is used to collect messages for message digests.
If messages are not removed from that Mailbox after a digest is created,
this Mailbox can be used as a mailing list archive.
Select the Enabled value for the Digesting and Archiving option
and follow the link next to that setting to modify the Digesting and Archiving
settings.
When the Digesting and Archiving option is enabled, all posted messages
are stored in a Mailbox created in the list owner Account. The LIST module
periodically checks that Mailbox and creates list digests and indexes.
A digest message contains a set of the messages posted on the mailing
list since the time when the previous digest was composed.
A digest message body contains the digest header, the table of contents
(TOC) listing all the messages in the digest, the TOC trailer, the posted
messages, and the digest trailer.
A list index message contains the same digest header, TOC, and TOC trailer,
but it does not contain the posted messages themselves and it does not
contain the digest trailer.
List index messages are created at the same time the list digest messages
are created. Digest messages are sent to the digest-mode subscribers, and
index messages are sent to the index-mode subscribers.
Generate Every
This setting specifies how often the LIST module should generate digest
(and index) messages for this list.
First Digest at
This setting specifies the time of the day when the first digest should be generated.
Note:if the Generate Every setting value is not more than 1 day, every day
the first digest is generated at the specified time. If this setting is set to 4:00,
the Generate Every setting is set to 1 Day, and the last digest was generated at 23:00 on
Monday, the next digest will be generated at 4:00 on Tuesday.
If the the Generate Every setting value is set to N days (N>1), the first digest is
generated at the specified time N days later: if this setting is set to 4:00,
the Generate Every setting is set to 5 Days, and the last digest was generated at 23:00
on Monday, the next digest will be generated at 4:00 on Friday.
if Larger than
This setting specifies the maximum size of the messages to be included
into one digest. If the total size of all messages posted since the last
digest was generated exceeds this limit, a new digest (and index) is generated
immediately, overriding the Generate Every and First Digest
at settings.
if has X messages
This setting specifies the maximum number of messages to be included
into one digest. As soon as the specified number of messages is posted,
a new digest is generated immediately.
Digest Subject
This text setting specifies the Subject header field for digest and
index messages created for this mailing list.
If the Prohibit Unmodified Digest Subjects
option is selected, the mailing list manager rejects all postings with
a reply prefix (Re:, Re>, etc.) followed by an unmodified
Digest Subject text.
Body Format
This setting specifies how the digest body should be formatted.
plain text
Digests are composed as plain text messages; individual messages
are separated with a line containing minus symbols.
standard MIME
Digests are composed in the MIME multipart/digest format, where the
first part has the text/plain Content-type and contains the digest TOC, and
other parts contain the messages (postings).
embedded MIME
Digests are composed in the MIME multipart/mixed format, where the
first part has the text/plain Content-type and contains the digest TOC, and
the second part uses the standard multipart/digest format and contains all
messages (postings).
Header
This text setting specifies the text to be included into all digest
and index messages before the Index Lines (Table of Contents).
Index Line
This setting specifies the format for an index entry. Like the service
text settings, the Index Line can (and should) have special symbol combination,
but these combinations are different.
For each posted message, values from the message are substituted into
the Index Line text and the resulting line is stored in the digest or index
message being composed.
Combination
Substituted with
^X
the message sequence number in the digest being composed
^F
the From header field of the message
^T
the Date header field of the message
^S
the Subject header field of the message
^I
the Message-Id header of the message
Index Trailer
This text setting specifies the text to be included into all digest
and index messages after the Index Lines.
Trailer
This text setting specifies the text to be included after the last
message in the digest.
All messages posted on a listname mailing list are stored in
the listname Mailbox in the list owner Account. When a
digest is being composed, the posted messages are retrieved from that Mailbox.
This Mailbox also serves as an archive for all posted messages, and this
archive can be searched via the user Web interface.
Each time after a digest is composed, the Mailbox is checked and the
oldest posted messages are removed to keep the archive Mailbox size within
the specified limits.
Maximum Archive Size
This setting specifies the maximum size of the archive Mailbox. After
a digest is generated, the new archive file can be generated or the oldest messages can
be removed from the Mailbox to keep the Mailbox size below the specified limit.
Messages to Keep
This setting specifies the maximum number of messages that can be
left in the archive Mailbox after a digest is generated.
Start new Archive every
This setting specifies when the new archive Mailbox should be created.
The old archive Mailbox becomes a submailbox with the name YYYY-MM-DD, where
YYYY specifies the year, MM specifies the month, and DD specifies the day when the
first archive message was stored.
Unless the Start New Archive option is set to never, a new archive is created
when the archive Mailbox size limit or the archived message number limit is exceeded.
If the Start New Archive option is set to never and the Maximum Archive Size option is set to zero,
all messages are removed from the archive Mailbox as soon as a digest is generated.
Browse Access
This setting specifies if this mailing list should appear in the Mailing
Lists section of the WebUser Interface.
nobody
The mailing list will not be available via the Web Interface.
anybody
The mailing list will be displayed as a browsable mailing list, and its archive can be used by anybody.
subscribers
The mailing list will be displayed as a browsable mailing list, but in order to browse its archive,
users should enter their E-mail address and the Confirmation ID (as the password). To retrieve
a forgotten Confirmation ID, a user can always send a message to
<listname-confirm@domain> and get the confirmation ID even if the list
subscription mode does not require confirmations.
If the subscriber (E-mail address) is a local CommuniGate Pro Account, then not only the confirmation ID,
but also the Account password can be used as the list access password.
clients
The mailing list will be displayed as a browsable mailing list, and can be browsed from
the Internet addresses included into the server Client IP Addresses list.
For users trying to view the list from outside the specified addresses/networks
this mode works as the subscribers mode: these users have to enter the
name/password pair (E-mail and Confirmaton ID) to browse the list.
If you are a system administrator or the list owner, you can access the
subscribers list page following the Subscribers
link on the Mailing List Settings page.
The Subscribers page contains the list of all E-mail addresses subscribed
to the mailing list. For each address additional information (such as the
subscriber's real name, number of bounces from this address, etc.) is listed.
Each address can be marked, and you can use the Mark All button to mark
all list subscribers. You can use the Filter field to display the subscribers
with matching addresses only.
Unsubscribe
Mark some subscribers and click this button to unsubscribe them from the list.
Depending on the current FeedBack setting value, the LIST module will either unsubscribe
them immediately or just send them confirmation requests. If the FeedBack setting (see below) value
is Send Welcome, the Good Bye messages are sent to unsubscribed addresses.
Mark Failed
Mark some subscribers and click this button to tell the LIST module that mail to those
addresses bounced. This can be useful in situations when the LIST module fails to process
bounce reports automatically, because they come in a non-standard format.
Clicking the Mark Failed button will result in the same actions (increased bounce counter, suspension, and warning
generation) as caused by receiving a non-fatal bounce from the marked address.
Set Postings
These controls allow you to change the moderation mode for the selected users. You can
select some subscribers and set their posting mode to moderated, prohibited, unmoderated, or special.
See the Posting Messages section for more details.
Set Mode
These controls allow you to change the subscription mode for the selected users.
See the Subscription Processing section for more details.
If the FeedBack setting (see below) value is set to ask Confirmation,
the subscription mode is not changed, but a confirmation request for the mode change
operation is sent to the marked subscribers.
You can manually add subscribers to the list. Enter the new subscriber
E-mail address press the Subscribe button.
Feedback
If this option is set to ask Confirmation, all operations performed result in
confirmation requests being sent to the specified subscriber address.
If this option is set to Send Welcome, confirmation requests are not generated,
and the subscription modes are changed immediately, but the Welcome and Good Bye messages
are sent to subscribers when you unsubscribe a user or subscribe a new user.
If this option is set to silently, no messages are sent to subscribers.
Single User
Use this field to enter an E-mail address of the user you want to subscribe to this list.
A new subscriber address can be specified as an E-mail address with a comment, as John Smith <johns@company.com> or johns@company.com
(John Smith), in this case the comment is stored the subscriber's real name.
Click the Subscribe button to subscribe the specified address.
You can use text files with E-mail addresses to add subscribers to mailing
lists. Open the Subscribers page, and use the
Import control to select a file with E-mail addresses. Click the Subscribe
button to add the addresses to the mailing list.
The text file should have one E-mail address per line, with several
optional fields on each line. If a line contains several fields, they should
be separated with the tabulation (TAB) symbol.
The first and the only required field is the E-mail address.
The second field specifies the subscription mode. The first field symbol
is checked. The symbols d and D require the DIGEST mode,
the symbols I and i - the INDEX mode, and the letters
f and F - the FEED mode. All other field symbols are
ignored. If the first symbol is not recognized or the field is absent,
the new user is subscribed in the Mailing List default mode.
The last field (if a line contains more than 2 fields) specifies the
real name of the new user.
The Mailing List manager checks the file format first. If the file format
is incorrect, no new user is subscribed. This allows you to fix the file
format and to try the same file: either all addresses are added, or none is added.
Note: The import file must be prepared on the client computer (on the computer you
use to run your browser). The browser allows you to upload files from disks connected to that
computer, not to the CommuniGate Pro Server computer.
Note: When using Netscape and some other Unix browsers, make sure that the file name ends
with the .txt suffix - otherwise the browser won't upload the file as a text one, and the file will be ignored.
Note: Some versions of the Netscape® browser for "classic" MacOS® do not convert the
MacOS text files (that use the CR symbol as the line separator) into CR-LF delimited
text files. You may see the "format error" messages if you try to import
a subscriber list from a MacOS computer using that browser. You should either use
a different browser, or you should convert the subscriber list into a CR-LF delimited
text file before importing it with that browser.
Note: If you are moving users from a different mailing list system, make sure you
have set the Feedback option to Silently - otherwise all inserted subscribers will receive
confirmation requests and/or Welcome messages.
You may want to subscribe List1 to List2, so all messages posted on the List2 list
are sent to the List1 subscribers, too.
After you have added the qualified address of the List1 (list1@domain1.dom) to the List2
subscribers list, add the qualified address of the List2 (list2@domain2.dom) to the List1
susbcribers list. Set the subscription mode to null, so messages will not go back
to the List2 list, and set the posting mode to special, so messages from List2
(which are auto-generated list messages) will be allowed for posting on List1.
The LIST module processes messages sent to listserver@localdomainname.
The module takes the List Server commands from the message body, processes those
commands, and composes a response message with the command execution results.
All commands sent to the above address apply to the mailing lists in the specified
Domain only (to the virtual list server in that Domain).
The messages with the List Server commands should be in the plain text format,
or in the mulitpart/alternative format containing a part in the plain text format.
Each List Server command is stored on one text line. Line starting with the
%, *, #, and ; symbols are not processed (comment lines).
The following commands are supported:
SUBSCRIBE listname [mode [confirmation ID]] SUB listname [mode [confirmation ID]]
These commands subscribe the message author to the listname mailing list. If the
mode is not specified, the default subscription mode is used.
This is equivalent to sending a message to the listname-on@localdomainname
address.
These commands unsubscribe the message author from the listname mailing list.
This is equivalent to sending a message to the listname-off@localdomainname
address.
CONFIRM listname GETID listname
These commands send the message author his/her listname subscription ConfirmationID (password).
This is equivalent to sending a message to the listname-confirm@localdomainname
address.
WHICH CHECK
These commands list the mailing lists (in this localdomainname Domain) the message author is subscribed to.
HELP
This command displays the list of supported commands.
QUIT FINISH
These commands tell the LIST module to stop processing. The rest of the message text is ignored.
The LIST module routes to itself all following addresses:
listname@domain
if the list listname exists in the domain Domain, or
listname addresses, if the mailing list listname exists in the Main Domain.
Messages to these addresses are processed as submissions to the specified mailing lists.
The LIST module detects addresses in the form listname-request@domain and listname-admin@domain
or listname-request and listname-admin.
Messages sent to these addresses are rerouted to the mailing list owner.
The LIST module also routes to itself the following addresses:
listname-xxx@domain and
listname-xxx.
The xxx suffix can be one of the following:

on, off, subscribe, unsubscribe, feed,
digest, index
