Please Helpppp...
It just dawned like that today.
No Webmail we can get in.
When you enter, you enter with error.

The following error is logged in the log:
Jul 12 16:47:59 robusto dovecot[1840]: imap-login: Disconnected: Input buffer full (no auth attempts in 0 secs): user=<>, rip=, lip=, secured, session=<PSsCMIGNRNh/AAAB>


If anyone knows how to clean it, I'll pay to clean it.
