If it is in select email accounts, you may need to check your mail filter files (like .qmail) and make sure the mail isn't being sent through multiple times.

On checking the archives I found some post saying it could be low memory that is causing this, at the time I was running at 1GB RAM, So I stepped to 3GB but dupes where still coming. I then upgraded my toaster hoping it would cure the problem but alas nothing. Today I decided to go under the hood and see what is happening.. Not so long I discovered the dupes had a slight change in the headers section like seen below -first email to come Content-Filter: maildrop-toaster Return-Path: <akisa...@domain.com> Delivered-To: domain.com-a...@domain.com Received: (qmail 19861 invoked by uid 89); 16 Aug 2011 16:40:48 -0000 -Second email to come Return-Path: <akisa...@domain.com> Delivered-To: a...@domain.com Received: (qmail 19861 invoked by uid 89); 16 Aug 2011 16:40:48 -0000 There seemed to be something else sending the second email so anyway I looked further and compared the .qmail file for two users one that was receiving duplicate and one not receiving them and this is what I found -Account not receiving duplicates [root@abram alex]# more ../akisakye/.qmail |/var/qmail/bin/preline /usr/bin/maildrop -A 'Content-Filter: maildrop-toaster' /etc/mail/mailfilter -Account receiving duplicates [root@abram alex]# more .qmail |/var/qmail/bin/preline /usr/bin/maildrop -A 'Content-Filter: maildrop-toaster' /etc/mail/mailfilter /home/vpopmail/domains/domain.com/alex/Maildir/ There was a second line in that file /home/vpopmail/domains/domain.com/alex/Maildir/ am not sure how it got there but as soon as I removed it, the duplicates stopped immediately. I am currently writing a script to help me do this edit for about 600 users I have on this system.
