I'm trying to create and access rule that denies certain source IP addresses
from making SMTP connections to my email server. I create the access rule
and put it at the top of the list but the connections are still happening.
It's a deny rule to block Port, Service: SMTP, Origin Server Port 25, TCP &
UDP, Specified 'ip addresses', Destination 'any'. Granted I have my email
NATed through a secondary IP address to the email server. Any ideas why this
isn't working? Thanks.
