I have a port forwarding rule setup to only accept
connections on port 25 from an IP address and a network block that is from a
hosted anti-spam server provided by our ISP. However, it doesn't appear to
be limiting to those IP addresses listed. Everything is configured
correctly, all checkboxes are checked, etc. If I telnet to the firewall
address on port 25 from an IP not listed as allowed I
receive:
220 myfirewallhostname.domainname.com ESMTP
Postfix
Why isn't the connection just dropped? Why am I
connecting to a Postfix service on the firewall? I am not running SMTP
proxy.
Thanks for the help!

But I am not well versed in these things so this could be normal?

Looks like a notice from Postfix telling you it can not look up the Blackhole
zones.
