Firewall Doesn't Block Email?

So I have a drop rule in the #1 spot - if anything comes from/to an IP address range - I don't care what type of connection it is - I want it to drop.

For some reason I'm still getting emails from those IP address ranges - how can I truly stop the connection from even happening?

See my setup as shown in the images...

hi,

you run the smtp-proxy... so mails are processed by the smtp-daemon and will be processed and did not come to the firewall-process..

You can try host/network blacklist under SMTP/Relaying but i think this will not work as expected.

Create a DNAT-Rule which DNATs the "Hackers" List to an IP-Adress which is not existent in your LAN.. then create an firewall-rule which drops that traffic.
