Default IMAP not accepting passwords

Hi.

After a server reboot IMAP has stoped working; It does not accept passwords. This is for Thunderburd, Evolution and Roundcube.

Code:
root@serv14:~# telnet XXXXX.com.br 143
Trying 66.7.2XX7.XX4...
Connected to XXXXs.com.br.
Escape character is '^]'.
* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS AUTH=PLAIN AUTH=LOGIN] Dovecot ready.
I use Ubunutu 12.04.2LTS and the latest ISPCONFIG 3,05RC1

Restart mysql and then check the mail.log for errors when you try to login with imap.

The log contains only pop3 login attempts, no imap connects. Please post the dovecot.conf file.

Yesterday I had one error in the log files after you asked me to restart MySQL.

Code:
Feb 4 09:13:52 serv14 dovecot: auth-worker: Error: mysql: Query failed, retrying: MySQL server has gone away

This error is ok as it indicates that mysql was restarted while dovecot was connected to mysql.

To ensure that this is not a firewall isue, please run:

iptables --flush

which will remove all rules until you reboot the server or restartthe firewall and try to connect to imap again.
