multiple emails from one pop account

[tmdroid]

I am getting duplicate messages delivered to my Droid 2 from my POP account. If I completely turn of my Droid 2 and restart it, the POP delivery is fixed (only one copy of the message gets delivered.) After a while (a couple days?) I start getting two-for-one again. Rebooting is the only way I found to fix this problem. My Droid's brain seems to be getting scrambled

Any suggestions would be appreciated.
