So, connexions to the (imap? smtp?) mail server time out. Can you run
wireshark on the server, and see what's happening? Does the server
have a correct route to the clients?
If it's smtp, then try telnet from a client to the server (telnet
192.168.1.1 25) on the inside of the firewall, while watching top on
the firewall. What does the load look like? Does the telnet session
time out? During which part of the connexion?
It could be your firewall rules are broken, and replies are being
dropped or something. Wireshark will tell you.
