Is this inbound or outbound?

For outbound, you just could deliver your outgoing mail to the mailserver of your ISP (smarthost).

Inbound is a bit more difficult: I solved that once by having a service on the internet relaying inbound mail through their servers to port 2525 of my server (which wasn’t blocked by ISP).
