IMAP not accepting passwords

[EckyBrazz]

Hi.

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

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

[till]

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