Return ReceiptsSenders can request return-receipts by including the Return-Receipt-To: header fields into messages. When a message containing a Return-Receipt-To: header field is delivered to a local Account, the Server generates a Delivery Notification message. That message is sent to the Return-Path address of the message, not to the address specified in the message Return-Receipt-To: header field. Address Testing
If a message has the
X-Special-Delivery: test
header field, the SMTP and Local Delivery modules do not send the message to its recipients.
The SMTP module connects to all hosts the message is addressed to, then the module sends all recipient addresses to those hosts, but it does not send the message itself. The Local Delivery module checks if the account exists, but the module does not try to apply the Account Rules to the message and the module does not store the message in the Account Inbox. This feature can be used to verify addresses on large mailing lists: if an address contains an unknown domain name, or the host is not unreachable, or if the host rejects a user address, an error message is generated in the regular way, and can be used to detect "bad" addresses and to "clean" the mailing list. Adding Required HeadersIf a message does not have a properly composed RFC header part, the Server adds an RFC header to the message. This header contains the required fields only. If a submitted message does not have a Date: header field, the Server adds one using the date and time when the message was submitted to the Server. If a submitted message does not have a Message-ID: header field, and the message was received from a "trusted source", the Server adds a Message-ID: field to the message. Legacy Mail EmulationThe CommuniGate Pro software package includes the command-line program mail (mail.exe for the Microsoft Windows platforms). You can use this program to submit messages to the CommuniGate Pro system, as you used the legacy mail program to submit messages to the sendmail MTA. mail [-EiInv] [-d base-directory] [-s subject] [-f from-address] [-c Cc-addresses] [-b bcc-addresses] to-addresses
The CommuniGate Pro software package includes the command-line program sendmail (sendmail.exe for the Microsoft Windows platforms). You can use this program to submit messages to the CommuniGate Pro system, using the interface of the legacy sendmail program. sendmail [-i] [-t] [-d base-directory] [-f from-address] [-F sender-name] [-V envid] [-Oparameter] [-oparameter] [-B body_type] [address, ...]
The CommuniGate Pro mail and sendmail commands use the Submitted folder feature. |
