Я именно там это и вычитал. Но не совсем понял: вроде бы есть в природе "родной" Courier MTA (аналог Postfix), но его почему-то особо не используют, а прикручивают "чужие" MTA.

The kicker: any message copied or moved to # this folder is will be E-mailed by the Courier-IMAP server, by running # the SENDMAIL program. Therefore, messages copied or moved to this # folder must be well-formed RFC-2822 messages, with the recipient list # specified in the To:, Cc:, and Bcc: headers. Courier-IMAP relies on # SENDMAIL to read the recipient list from these headers (and delete the Bcc: # header) by running the command "$SENDMAIL -oi -t -f $SENDER", with the # message piped on standard input. $SENDER will be the return address # of the message, which is set by the authentication module. # # DO NOT MODIFY SENDMAIL, below, unless you know what you're doing. # SENDMAIL=/usr/bin/sendmail ##NAME: HEADERFROM:0 # # For administrative and oversight purposes, the return address, $SENDER # will also be saved in the X-IMAP-Sender mail header.
