SL Mail.app issues with POP accounts

[Shogododdo]

I'm experiencing a really weird issue since upgrading to SL. I have a gmail account (working fine) and several POP accounts including YMAIL. This is what is happening, every few days or so. The POP accounts are refreshing the exiting mail in the inbox and marking them as unread (for no apparent reason)

Not all but the vast majority of existing messages.

Anyone else experiencing this behaviour ?

Yes, it is really annoying. I "fixed" it with a restored version from Time Machine but the problem has since come back and is happening every day. Anyone know of a fix?

I restored a version of the inbox prior to the unread messages being populated.

Despite deleting the 3 affected POP accounts and recreating them, all 3 have suffered the problem again. This time it appears more prevelant, occurring twice in 3 days.

arrrrgggghhhh.

P.S.
I have raised a RADAR bug against Apple. (RADAR://#7274949)
