Azure firewall application rule does not support non-http80/http8080/https443 protocol, for example SMTP. Please add the new feature.
In order to inspect access to smtp.office365.com through Azure firewall, and leverage target FQDN in application rule, please add SMTP protocol support since currently AFW does not support non-http80/http8080/https443 protocol.
Guys, WE NEED IT! We recently created en environment and our devs use SMTP.GMAIL.COM:587, there are push notification services for Apple and Android. Those are on completely different ports!
And we will have PCI compliance certification!
