We run postfix on our campus mail relays (5 of them) which deliver mail to
Cyrus using LMTP. Our cyrus server is a separate box. On the mail
relays, postfix is configured with a transport map to shove mail for one
domain to cyrus over LMTP. On the cyrus server, we use a hosts.deny file
to restrict LMTP connections to just the mail relays, so that people
cannot inject mail and bypass our filters. Make sure you have set lmtpd
to "preauth" the connections using the "-a" option, like so:
lmtp cmd="/usr/local/cyrus/bin/lmtpd -a" listen="lmtp" prefork=0
Let me know if you have more questions.
