Hello m290 + fw 12.12.3

This works great matching mail server hostnames

The proxy examines the initial HELO/EHLO responses when the SMTP session is initialized. The default rules for the SMTP-Incoming proxy action make sure that packets with greetings that are too long, or include characters that are not correct or expected, are denied. You can add, delete, or modify rules. <<

Is there a way to match its rdns?

if not a greeting rule, maybe a packet rule?
