(nice combination :-)



You may create two zones : "smtp1.attglobal.net." and "smtp2.attglobal.net." 
both with a single "A" record (in addition to the SOA and NS records) The A
records should have the IP of your internal nameserver.

This will however affect your internal networks possibiyties to deliver 
mail to the same 2 servers ...  A better way could be to have your road-warriors 
to use a vpn to your home-net and send mail this way.
