Mail sending/receiving from wrong account
I have three accounts in Mail, a personal account, a work account, and a Mobile Me account. For some reason, sometimes mail is sent from the wrong account.
Here's the steps that happen:
1) Receive message at my personal account. (Note: the same behavior happens when replying both from the all-encompassing "Inbox" and the Inbox for the account.)
2) When I reply to the message, it shows that it's being sent from the personal account. The reply-to field is blank.
3) When I receive a reply to that message back, it comes to my work account.
4) Replying to that message sends it from my work account.
