My MX DNS record gives the address of my external firewall (1.2.3.4, for
example), which does NAT and forwards trafic on port 25 to my MailScanner
mail server, which would be, for example, 192.168.1.2 and then MS server
sends the filtered messages to my internal firewall (192.168.1.3), which
forwards the packets to the Microsoft Exchange server.

We are a small office (8 users), so we use basic networking equipment.
