Topic: Getting emails from 'email@example.com' Temporary lookup fail
I'm struggling to solve this why I get emails to 'root' notifying me Temporary lookup failure
The full body email I'm getting is (I changed the real domain name to @mydomain.net ):
Return-Path: <firstname.lastname@example.org> Delivered-To: email@example.com Received: by mydomain.net (Postfix) id ED4FA230436; Sat, 6 Nov 2010 21:58:56 +0100 (CET) Delivered-To: firstname.lastname@example.org Received: by mydomain.net (Postfix) id EAF9B230415; Sat, 6 Nov 2010 21:58:56 +0100 (CET) Date: Sat, 6 Nov 2010 21:58:56 +0100 (CET) From: MAILER-DAEMON@mydomain.net (Mail Delivery System) To: email@example.com (Postmaster) Subject: Postfix SMTP server: errors from unknown[18.104.22.168] Message-Id: <20101106205856.EAF9B230415@mydomain.net> Transcript of session follows. Out: 220 mydomain.net ESMTP Postfix In: HELO 22.214.171.124 Out: 250 mydomain.net In: MAIL FROM:<firstname.lastname@example.org> Out: 250 2.1.0 Ok In: RCPT TO:<email@example.com> Out: 451 4.3.0 <firstname.lastname@example.org>: Temporary lookup failure Session aborted, reason: lost connection
and I'm getting awful lot of these emails (like 10/min)...
This is happening after I had a server crashed with CentOS 5.4 and iRedMail 0.5.1 (as I recall from my memory) and now installed CentOS 5.5 with iRedMail 0.6.1 and then moved some config files for Postfix and Amavis to this new server.
I know it must be some 'new' configuration in Postfix which didn't exist before, but I can't find it.
This wasn't happening before on 'old server'.
I kindly please for some help.
