Mail keeps rejecting my email password, even though its correct, to the pint of utter insanity. Every couple of weeks, Mail will actually interrupt everything with a dialog box telling you that your e-mail password is incorrect or has been rejected, and asks that you re-enter the password –even though the existing password is perfectly correct, of course!"
