Reading around in these forums, I learned that the proxies take precedence over the packet filter rules. Simple enough.
If my Astaro is acting as an MX only, and has the host-based relay (Mail>SMTP>Relaying) populated with my internal mail servers, do I need anything in the "Network Security > Packet Filter" rule list for "Internal Network-to-Any"?
I'm thinking the Packet Filter should be empty of rules in this case?
