Hi all!
We have been running Postfix and Amavisd-new for quite some time,
without any problem... until we upgraded our FreeBSD from 4.11 to
5.4-RELEASE.
We are currently running:
FreeBSD: 5.4-RELEASE
Postfix: 2.3-20060207
Amavisd: amavisd-new-20030616-p5 (ancient, I know...)
Since the upgrade, at peak times, the messages take a lot of time to be
sent. They usually took 2s to 3s at most, now they always take 10s+
(sometimes more than 2min or 3min!).
From the amavis.log, it seems that the problem is in the SMTP-* and
fwd-* sections. Always.
Here are the logs of a typical message with this probleam (edited for
clarity sake):

From the fwd-connect I'd think about a reverse DNS lookup timeout...?
Do you have rDNS activated and if yes, is the host able to resolve
127.0.0.1 or the local IP...?
