Zimbra Version: Zimbra 5.0.0_BETA3_1276.RHEL5_64.FOSS Aug 22, 2007.
Distro: CentOS5 86_64
Hello all. I am experiencing a weired issue with Zimbra. First let me explain my setup.
I am running a Barracuda SPAM Firewall Model 400 on the front side that all of my domains MX records point to. After the email has been filtered, it is delivered to my Zimbra server. I have multiple domains and about 100 users. I am currently running Zimbra 5.0.0_BETA3_1276.RHEL5_64.FOSS Aug 22, 2007 on a CentOS5 machine.
The issue is that after a user logs into the Zimbra web interface and then goes back to using their regular mail client (Thunderbird or Outlook), they start experiencing emails being duplicated and some being changed and over written. Say five different people send me five different emails. All four of the emails that come in first would be completely over written and changed to look exactly like the fifth email that came in including headers, body, and message. There is also duplication going on.
If anyone has any ideas what is going on I would greatly appreciate the help. Thanks!
