Restarted firewall: problem gone.

Thank you very much

Filippo

Hello,

suddenly I can no more login in my IMAP server...

None of my users can login in his mailbox, neither from cellphone, nor from local, nor from... anywhere.

My mercury server is 4.74; no SSL; passwords are correct; users are correct...

Here is the session log

Any idea?

Please help, because on monday my office is open...

Connections are established, but the client fails to react to the response sent from the server. If the server otherwise works normally with regards to networking, and the problem persists after a server restart, it looks like some kind of routing problem or other kind of network issue. I would probably try restarting switches and other networking devices to see if that makes any difference.
