In order for this to work, your MX records will have to point to the
publicly routable address of the firewall, and the firewall will have to
redirect incoming port 25 to port 25 of the internal qmail mail server
address.
In other words, if your firewall has an external address of 1.2.3.4,
an internal address of 192.168.1.1, and your qmail server has 192.168.1.2,
then your firewall must forward inbound traffic to 1.2.3.4:25 to
192.168.1.2:25. Your MX records will point to 1.2.3.4.
But, yes, it works without any problems that I've ever seen.
