Hi, i just installed version 2.3, we have an internal mail server behind pfsense on orange zone (dmz) with 25 port forwarding to the orange zone mail server ip.
I just tried to implement smtp proxy, i turned it on and disabled port forwarding (25) , then added one of our mail server`s domain into Incoming domain tab with its respective internal ip but the server cannot receive any mail.
This is what log show:
postfix/smtpd[6824]: NOQUEUE: reject: RCPT from mail-gw0-f45.google.com[74.125.83.45]: 450 4.1.1 <@.com>: Recipient address rejected: undeliverable address: mail for [x.x.x.x] loops back to myself; from=<
xxxx@gmail.com> to=<@.com> proto=ESMTP helo=<mail-gw0-f45.google.com>
am i missing something?
sorry about my english
thanks a lot!
I found that it was a FQDN issue, my mail server name was the same as the Postfix`s name
