Watch out for the !
Isn't it amazing how so many people can type "linuxpakistan.net" into their browsers but not "google.com"?

what i meant was wether ur firewall is not blocking outgoing SMTP connections as u can receive mails but not able to send mails using your mail server.

if you can telnet to any outside SMTP server on port 25 then it means outgoing SMTP is working through ur firewall, if telnet fails then ur firewall is blocking outgoing SMTP requests and u'll have to chk ur firewall rules.
hail to linux!!!

AOA,

Sorry for the late reply.

My complete iptables script initially loads all the required modules, which include many of the modules listed.

The problem is not about IPTABLES, i know my rules are correct, still dont know why its not working.

The mail server is a pre-configured IBM Server using DOMINO. I dont have any access to the server, cant even open it.

I will try something new after eid then will let you all know whether it worked or not.

send mail from the server while running tcpdump to watch the packets on the internal interface.
