This is not the answer. The filtering must happen on the IMAP server, over which you have no control.

comment Why not assign the hostname to the loopback address in /etc/hosts?
I ran into the second case this morning. Configured a server to listen to the IP address given by its fully qualified domain name on a particular port, then tested the connection using telnet, then told a remote collaborator that the server was up and running. He couldn't connect. It turns out neither the server software nor telnet do a DNS lookup: both resolve to 127.0.1.1, so my telnet command was connecting, but no remote connections were possible.

comment sshd running at 100%
Snother idea is to check logs or issue lsof to find out whether any ssh connections are being made or attempted at that time.

comment How to block ports (in Linux) based on the IP used to connect?
My guess is that the downvote is because you didn't explain where exactly you got stuck. It's as if you didn't even try.

man iptables or use Google. I don't find this stuff (e.g. 'chains' in iptables) very easy but I do find the answers that way. BTW I think it's better and easier to just block all incoming traffic (rule 1) and then open port 80 (rule 2).
