Deny access to smtp to specific IP range

[NetX]

Hi,

I have configured some iptables rules, but I need deny access to smtp for all IPs starting with 200.24.*.*

How can I setup a firewall for that?

Is there some tool to help?

I will appreciate your help

Hi,

You can place the domain names or the IPs in the /etc/spammers to avoid them.

Thanks.
