problem sending/recieving mails

Hi all,

I ave setup a Fedora server as LAN gateway and also as a transparent 
proxy server but all client "passing through" that server are enable to 
send or receive mails.

The mail server is hosted on the same LAN running mdaemon, both servers 
are on private IP block(192.168.0.0/24). Am using cisco router to do 
port forwading for mailserver(25,110,143) ports.

If i eliminate Fedora box and direct traffic from LAN to cisco router 
everything works.

My question is why is it when i use Fedora box as LAN gateway clients 
are unable to send/receive mails? I ave done nating on that box.

Fodora 12 fully updated(as at 2/11/2010).

Start simple.  Does telnet mailserver 25 from the clients work?
