Mail can't connect to accounts

Hey guys.

I've been having this problem since yesterday.


Mail keeps giving me the message:

"Mail can't connect to the account
"xxxxxx@att.net"

"Enter the password for user "xxxxx@att.net""


I have 8 different email accounts and they are all giving me the same message.

They are all IMAP accounts that have been working fine for 2+ months other than an occasional hiccup where I'd get that message for an account or two but relaunching mail 5 minutes or a few hours later it would be fine.

I keep entering the passwords (auto enter) and problem persists. Also ran keychain verification and there are no problems there.

Any ideas?
