Question Email duplication in server!


Dear All:

Suddenly email users are getting many duplicate mails in their outlook. It shows same from webmail and by "mutt -f imap://user@maildomain/". It's a Postfix, Dovecot Mail server. Please suggest me how to troubleshoot and what should be the reason behind this.

FYI, there is no aliases created now...

Regards,
-
T. Paul

Exclamation

After checking many parts and appliances of whole network, I have discovered that sometimes there is packet loss to internet cloud and sometimes it's fine. It is suspected that the problem of email duplication arisen here is due to packet loss.

Experienced Guys: now, please let me be confirmed that is it right that there might be any such duplication problem due to packet loss?

Friend I am sorry but here, I've changed something for company security purpose and for your convenience,

* ISP-DOMAIN.com is ISP's domain name
* MY-MAIL-SERVER-DOMAIN.com should be replaced with the real mail server
* 123.123.123.162 is equivalent to real mail server ip address (x.x.x.162)
* 223.223.223.66 is (x.x.x.66) probably any router or any other appliance at ISP side
* I also have sent email to abuse@mxtoolbox.com not to send message anymore
* The reply has been a little bigger, I am sorry for that

At a quick peek, it seems normal to me. Each mailid get delivered only once and then removed, and messages seem to be different ones (looking at message sizes) so I can't spot duplicates there. Were any of these messages duplicates?

Dear tva:

I have checked some duplicated mail's associate log report, but there is only single session per duplicated mail. Might there have any dovecot issue?

Can you check at filesystem level if there is duplicates? I also use Dovecot / Postfix setup and have never run into something like that. Shouldn't think that it's Dovecot problem but you should check logs for that too, if there is something strange..

Unhappy

my dovecot version is 2.0.9 and postfix version is 2.6.6, might there have any problem with these old version?

I have troubleshooted in some other ways, even I have configured the server again from the scratch, but the result is same. Someone has suggested to check my LAN environment, because there may have infected PC(s) which are doing such. Please check the below Headers of same duplicated mails, if you can get any point:

Thanks everyone for trying to help me...

Got the solution: It's another MTA having less priority value as mail server in DNS was causing the total duplication problem.

This page has helped me to understand and sort out the problem. Thanks to the page author and you all again.
