Here's a weird one for you....

We're running GroupWise 8 SP1 with eDirectory 8.8 SP5 on Windows 2008 Server Standard 32-bit without hyper-V SP2 on two servers. Server A is acting as the internal GWIA and also has the PO and an MTA on it. Server B is of course the external GWIA with POP3 active and an MTA to pass the email to the internal GWIA. Server B is located within our DMZ.

Setting aside the performance issues I'm having (, everything is functioning as it should. However, it has come to my attention that some of our POP3 users external to the firm are receiving random old emails that are showing up as new emails with new timestamps!

As you can imagine, this is a very frustrating problem especially since everything looks like it's running smoothly. I've done a TID search and have combed the forums for the past hour looking for something. Has anyone experienced this problem before? Any help would be greatly appreciated. Thanks!
