Unable to logon to the server using Secure Password Authentication. Account: 'myemail@mydomain.com', Server: 'mail.mydomain.com', Protocol: POP3, Server Response: '-ERR Command not implemented', Port: 110, Secure(SSL): No, Server Error: 0x800CCC90, Error Number: 0x800CCC18
Solution: Turn off "Logon using Secure Password Authentication (SPA)", as this is not required for receiving email. Authentication is only required when sending outgoing email via our servers.
