Hello.

My server was working fine until I log in and fail several time for a user account trough /mail url.

After that my server crashed. I can't get to any of the url, /ireadmin or /mail. All serves status are ok... restarted server, stop and restart service and nothing.

The mail log dont show any error trace.

BTW I have a similar mirror server, just different host name. That one is working fine.
