Given the case that:
1. postfix is a backup MX for foo.com
2. this postfix uses other MTA as relay_host
When the primary MX for foo.com is down, messages to u...@foo.com will be
delivered into backup MX. And, backup MX delivers the message to
relay_host, which find that primary MX can't be reachable, so relay_host
deliver message to backup MX again.
Will this delivery loop happen in real world?
as I answered in my last mail in previous thread:
https://marc.info/?l=postfix-users&m=168466205702341&w=2
you should set-up transport map for example.com directly to primary server
to avoid this loop:
example.com relay:[primary-mx.example.com]
you have replied to my previous mail, which I didn't respond to, as I
expected you to read my followup.
