Hi, Please understand, the logs belongs to dovecot IMAP server, that 
means you cannot login using (web interface / IMAP client) 
"squirrelmail" etc. but i tried to telnet to your server, to see the 
behavior but could not. it seems that your postfix server is also down. 
following could be the cause. Is it virtual user environment? CentOS 5 
or 6.0? please explain, what are you doing, are you never able to login? 
Cannot help with this info.
