Outlook & Duplicates

Hello,

I have at least two clients using Outlook 2007 that continuously receive every e-mail twice.

I'm using Dovecot so it's definitely no the MBOX/Squirrelmail issue. (Dealt with that awhile back.)

I've tried searching, but haven't found anyone with the same problem.

I'm running CentOS 5.0 (I was sure it was 5.1, but DA says 5.0)

Apache 2.2.6
DirectAdmin 1.33.7
Exim 4.67
MySQL 5.0.45
Named 9.3.3rc2
ProFTPd 1.3.1rc3
dovecot 1.1.7

It only affects outlook, and not blackberry, iphone, apple mail, etc.

For some reason the duplicates are usually 1-2KB different in size. Headers are identical, I can't figure it out what might be causing it, except maybe Spam Assassin?

If you tell me what logs I can produce, etc to help figure this one out I'd gladly do so. The reason I use DA is because I'm not a Linux junkie... haha any help is appreciated!

Would it be an idea to update Dovecot to see if it fixes the problem?

Hi quadium

I had the exact same problem on my server. The problem would only occur on random email accounts and at random times, so there was no pattern...

I haven't had this problem since I upgraded and re-built the dovecot package again...

So try that and see what happens?

There wouldn't happen to be one of those handy guides to follow for this, would there?

Thanks. I'll give that a try and hopefully it'll resolve the issue!
