Thanks Charles...
Someone else can help me?
I cannot receive any mail with my client thunderbird.
Postfix send mail ok... and the mail they are received by server (i can read it
inside webmin), but even squirrelmail give me a imap login error.
Im running a Debian Linux 5

Thanks for some reply and help.

dovecot-auth process is hanging for some reason. Do you have any error
messages from it in the logs?
