In UTM Email protection isn't active.
For current email sec appliance from inside to outside we created NAT rule.
And then on physical switch we catch smtp port 22 and forward it to outside from one public IP address.
For service I create custom SMTP rule (Default: 1:4***xx->25) I create 25->25
How can we create rule when UTM send Notifications or Report so that NAT rule is working
How Headers look

So as you can see. I need to change 45639 to port 25 and I need Send over DMZ (address) so it can be intercepted on physical switch.
