I have a strange phenomenon that I have the following message in my rejectlog:
2012-04-13 14:19:17 1SIfTB-0007y2-5S H=(mail.myhost.com) [0.0.0.0] F=<firstname.lastname@example.org> temporarily rejected after DATA Envelope-from: <email@example.com> Envelope-to: <firstname.lastname@example.org> P Received: from [0.0.0.0] (helo=mail.myhost.com) by mail.myhost.com with esmtp (Exim 4.34) id 1SIfTB-0007y2-5S for email@example.com; Fri, 13 Apr 2012 14:19:17 +0200 * Return-Path: <firstname.lastname@example.org> I Message-ID: <email@example.com> Date: Fri, 13 Apr 2012 14:19:17 +0200 Subject: My Subject F From: firstname.lastname@example.org T To: email@example.com MIME-Version: 1.0 Content-Type: multipart/alternative; boundary="_=_swift_v4_13343195574f8819c529888_=_"
(Please note that myhost.com, otherhost.com, mywebhost.com and otherhost2.com are fictitious in order to maintain privacy)
The client (SwiftMailer) spits out the following error message:
Expected response code 250 but got code "451", with message "451 Temporary local problem - please try later"
The weird thing is, that exim only reports the error message above in its rejectlog - there is no sign of the mail in mainlog, paniclog, mail.log, syslog or any other logfile.
It's an Exim 4.34 and works fine besides these strange rejects...
