Mail Problem [courier]

[sebby]

I`ve clean my /var/log/maillog ,restarted imap and now here is the log:

Code:

localhost# cat /var/log/maillog
Jan 24 03:21:54 localhost imapd: LOGIN FAILED, user=sebby@pcnet.ws, ip=[::ffff:127.0.0.1]
Jan 24 03:21:54 localhost imapd: authentication error: Input/output error

EDIT: This is how it looks after i telnet localhost 110 (pop3)

Code:

localhost# cat /var/log/maillog
