Re: [Dovecot] Unexplained MDA bounce backs
Dean Manners, on 1/14/2008 3:39 AM, said the following: -Postfix 2.3.4 with MySQL backend -Dovecot 1.0.rc26 with MySQL backend, using only deliver. Both of these are old, but the dovecot is very possibly the problem - if memory serves, that version was buggy. You really need to update to a current release version (1.0.11 is current), whether it fixes this particular problem or not. I also strongly recommend updating postfix... 2.3.4 is over a year - and more importantly 9 patch levels AND a full release+6 patch levels - old, with another major release (2.5) imminent. Lots of good reasons to upgrade postfix, but normal caveats apply - ie, read the release notes to see if anything changed that will require you to modify current config files. -- Best regards, Charles
[Dovecot] Unexplained MDA bounce backs
I have recently noticed that some of our internal mailer scripts are causing Dovecot-LDA to generate Mailer Delivery Subsystem messages. The following Dovecot-LDA message is generated: Message body Your message was automatically rejected by Dovecot Mail Delivery Agent. The following reason was given: Unknown error Message body Message header Return-Path: Delivered-To: [EMAIL PROTECTED] Received: by mymachine.x (Postfix, from userid 5000) id 5772568300; Mon, 14 Jan 2008 18:00:56 +1100 (EST) Message-ID: <[EMAIL PROTECTED]> Date: Mon, 14 Jan 2008 18:00:55 +1100 From: Mail Delivery Subsystem <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> MIME-Version: 1.0 Content-Type: multipart/report; report-type=disposition-notification; boundary="21506/mailfilter02" Subject: Automatically rejected mail Auto-Submitted: auto-replied (rejected) Precedence: bulk Message header Initially I thought these were being caused by Delivery-Receipt requests, however have since tested this and is not the case. I have tried to snoop through the logs (unfortunately on a very busy mail hub) using the Message-ID, however this doesn't seem to lead me back to the original message - only the MDA notification. I can only ascertain that its isolated to our scripts, as the bounces@ address is specifically used by them. Any ideas what would cause/trigger the "Unknown error" automatic rejects ? System config is -Postfix 2.3.4 with MySQL backend -Dovecot 1.0.rc26 with MySQL backend, using only deliver. All mail deliveries are otherwise fine. Regards __ Dean Manners
