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?
I have a block of 5 static IPs - (18.104.22.168 - 22.214.171.124) 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
