Re: iredmail stopped working

Have you got any logs? Or are willing to give me SSH Access?

Re: iredmail stopped working

About "crash", "down", do you mean the server was shut down, or some network services (e.g. imap/smtp/pop3) were not accessible?
Did you check iptables firewall rules? If client had too many password failures, Fail2ban will invoke iptables to block this client IP address.

Is your IP address one of above 3?
If you can telnet to port 25 on localhost, that might be caused by iptables firewall rules. Maybe you have too many password failures, and Fail2ban invokes iptables to block your IP address.

I suggest you empty current iptables firewall rules first, then try again:

# /etc/init.d/iptables stop
