Some of my email accounts are giving "Authentication failed" message after working for over 12 months. The accounts and passwords are valid - I can access them on other systems and can ping the servers. Some other accounts are still working properly. As far as I know, nothing has been changed - unless there was an automatic update of something? I have tried removing passwords, setting up new accounts in the same name - nothing is working. Any ideas?
