HTTP Proxy Stop SMTP Traffic
I'm trying to create an HTTP policy proxy that essentially stops SMPT traffic on port 80. Is this realistic?

STMP traffic will usually be on port25/tcp. If there is an http proxy in place and SMTP were trying to traverse port 80 -and- matched that firewall rule, it should be dropped.

Are you asking about blocking web mail, such as access to Gmail?
Thanks perfect.
I have a block of 5 static IPs - (1.2.3.4 - 1.2.3.8) SMTP email is going out on the Ip ending in 4. How do I create a rule that will direct email to go out using the IP ending in 5 instead of 4?
Use Dynamic NAT on your outgoing SMTP policy.
You can specify the external IP addr to be used there.
That option is on the Advanced tab of a policy in Policy manager
Awesome!!
