Hello.

A few tips on how to approach a potential rule/routing problem:

1. What does the log say in the Firewall about the traffic? Is it blocked or is it allowed by a rule?
1.1. If the traffic is blocked by e.g. "Default_Drop_Rule" it means that you do not have an IP policy that allows the traffic.
1.2. If the traffic is allowed, examine which rule it is that is triggering. Maybe you need to activate NAT or that you have enabled an ALG/Protocol that is scanning POP3/SMTP and it is not correctly configured? E.g. that AllowTLS is not enabled and your client is using TLS/encryption.
2. For testing purposes, you could use a service that is basically unrestricted. By using the "all_services" or maybe "all_tcp" or other you allow pretty much all protocols or ports. Then you can verify if the problem is related to the service or not and you can narrow down the problem.

Best regards
