Each Helm gets its own gateway server with static IP address that the Helm establishes a VPN connection with. Port 25 is open on the gateway and the packets are forwarded to the Helm. This is how we work around residential ISPs blocking port 25.

This doesn't necessarily mean you're not violating their ToS.
