I have set up my mailserver using and it worked until today, where I can not access the server using IMAP.
The error I see in dovecot.log is

2012-02-09 16:37:40 imap-login: Info: Disconnected (no auth attempts): rip=*myip*, lip=*serverip*, TLS handshaking: SSL_accept() failed: error:14094417:SSL routines:SSL3_READ_BYTES:sslv3 alert illegal parameter

But do anybody know, how I can fix it so I do not need to read the e-mail using webmail, 'cause I can connect to the server using webmail (Squirrelmail)

I tried to change the setting in Thunderbird to not use SSL/TLS and just use clear password, but that did not do the trick
