Mail keeps asking for password

Hi all,
There I was, happily running SL when all of a sudden, every time Mail wants to check the server for new mail, it asks me for the password. I duly enter the password, click on the "keychain remember" box, and it gets the mail. But next time it happens all over again.
Anyone heard of this issue? I don't believe I changed anything at my end.
Thanks and a Happy Xmas to all.

bump for answer. I'm having the same problem with mine.

Been looking at the forums via Apple's support website, and it seems there are many people with this issue. Apple, naturally, haven't acknowledged there is a bug, but there must be!
Would like to think they fix this sooner rather than later.

I had that issue with an Snow Leopard upgraded from 10.5. All I remember doing was open Keychain Access from Utilities and delete the entries for the Mail POP passwords and reopen mail and it worked since then. I can't remember the exact entries but I am sure you will find them.
