Block smtp traffic

[Darryl Romano]

If the server that you are running this rule on is the same server as your
smtp, then you should change the rule to -A INPUT.

Subject: Block smtp traffic

Hi list, this is my first post.

I had a internet gateway that I want to block all traffic send to smtp
ports ( 25 tcp ). I had done this:
iptables -A FORWARD -i eth1 -p tcp --dport 25 -j DROP

and I cannot make this rule work, my user still can connect to port
25.... I try to change from drop to reject and still the same problem,
where can I look for to make this work ?

thanks, Allan
