Hello guys!
I was reading the smtp_fallback_relay doc at
http://www.postfix.org/postconf.5.html#smtp_fallback_relay and couldn't be able
to make it work.
It says:
smtp_fallback_relay (default: $fallback_relay)
[…]
With bulk email deliveries, it can be beneficial to run the fallback relay MTA
on the same host, so that it can reuse the sender IP address. This speeds up
deliveries that are delayed by IP-based reputation systems (greylist, etc.).
The fallback relays must be SMTP destinations. Specify a domain, host,
host:port, [host]:port, [address] or [address]:port; the form [host] turns off
MX lookups. If you specify multiple SMTP destinations, Postfix will try them in
the specified order.
…
So I had on my main.cf this of host-x.domain server:
smtp_fallback_relay = host-x.domain
And the logs just shows this:
postfix/error[18333]: 84F911A02BC58: to=<[email protected]>, relay=none,
delay=1143, delays=0/1143/0/0, dsn=4.3.5, status=deferred (delivery temporarily
suspended: mail for host-x.domain loops back to myself)
Any idea of what I'm doing wrong?
Thanks in advance.
