Lets assume that worked, check the gatway/router address on the mac server
points to the private ip of the firewall.  Now that shpuld work for you.

If you didnt pass the first step there is a problem on your mail server.

This could be a routing problem caused by change of ip on tgw inside of the
firewall meaning the mac server is no longer using the correct IP as its
gateway IP.
