Now just make sure any "roaming" users have authenticated SMTP enabled in their mail clients and you're set to go. (I'd also make sure they using encryption, especially if they use LOGIN or PLAIN authentication.)
I suspect that he had a NAT firewall which forwarded all incoming port 25 connections to his server.
Naturally, everyone who would connect to the server would have, from the server's perspective, the firewall's IP address, to which he granted relaying privileges.
