Hi all,
I'm working on a Postfix+Cyrus IMAPd system, and am looking at whether to
have Postfix deliver mail to Cyrus via a unix lmtp socket
(/var/imap/socket/lmtp)
in /etc/postfix/main.cf:
mailbox_transport (or local_transport) = lmtp:unix:/var/imap/socket/lmtp
in /etc/postfix/master.cf:
lmtp unix - - n - - lmtp
and in /etc/cyrus.conf under SERVICES:
lmtpunix cmd="lmtpd" listen="/var/imap/socket/lmtp" prefork=1
**OR** use /usr/cyrus/bin/deliver as follows:
in /etc/postfix/master.cf
cyrus unix - n n - - pipe
flags= user=cyrus argv=/usr/cyrus/bin/deliver -r ${sender} -m
${extension} ${user}
in /etc/postfix/main.cf:
mailbox_transport = cyrus
Are there any performance/security issues using one method versus the
other? Would one offer me greater flexibility in doing spam filtering (via
regex and/or blacklists), antivirus checking, etc?
We handle mail for 3 domains, and don't have anything too fancy set up for
user authentication on the IMAP side...
Thanks much!
Thomas Hannan
