here is the latest error message:
There was a problem logging onto your mail server. Your Password was rejected. Account: 'mit@mydomain.com', Server: 'mail.mit.com', Protocol: POP3, Server Response: '-ERR Logon failure: unknown user name or bad password.', Port: 110, Secure(SSL): No, Server Error: 0x800CCC90, Error Number: 0x800CCC92
the server is rejecting either your username and/or your password ... verify that they are both correct in your script ... if so, you might need to fix your script to expect delays from the prompt ...
check your PAM config file /etc/pam.d/pop3 if your system have PAM enabled. I believe the PAM configuration for your POP account is having a problem.
