You're mistaken, mail sent *to* the user has no need for and does not rely on SASL. So it is completely unaffected by the password change. On the other hand, mail attempted to be sent *by* the user, is affected, because the user can no longer authenticate. The fix is to make sure that the password expected by the server is the same one that is configured in the user's mail client. Change either end or both. -- Viktor.
