I have a server running postfix on port 25 and a secondary mail
platform listening on port 2525. I have tried many combinations of
settings but keep getting:
Feb 12 08:34:43 server1 postfix/smtp[11104]: 19183EB01F0:
to=<u...@domain.com>, relay=none, delay=6.9, delays=6.9/0.01/0/0,
dsn=5.4.6, status=bounced (mail for domain.com loops back to myself)
My server name is "server1.domain.com" and my mail platform on 2525 is
hosting "domain.com". What settings in my main.cf will prevent
postfix from thinking this is a loop?
[root@server1 log]# postconf -n

permit
unknown_local_recipient_reject_code = 550
/etc/postfix/transport
domain.com smtp:[192.168.1.3]:2525
I have tried limiting postfix to listening only on loopback and
192.168.1.1:25 and the mail platform to listen only on 192.168.1.3:25
then adjusting the transport file accordingly but it still bounces the
message.
Thanks for the help.
