When i try to login to my email account on Microsoft outlook 2010 and text account settings it gives me this error:
Log onto incoming mail server (IMAP): The connection to the server was interrupted. If this problem continues, contact your server administrator or Internet service provider (ISP).
The mail.err log:
Mar 17 13:43:30 mail dovecot: imap-login: Error: Timeout waiting for handshake from auth server. my pid=1882, input bytes=0
Mar 17 13:43:59 mail dovecot: auth: Fatal: APOP mechanism can’t be supported with given passdbs
Mar 17 13:43:59 mail dovecot: master: Error: service(auth): command startup failed, throttling for 60 secs
Mar 17 13:44:32 mail dovecot: imap-login: Error: Timeout waiting for handshake from auth server. my pid=1886, input bytes=0
And this is for IMAP/POP3 neither work. SMTP is working perfectly fine though.
