Address Extensions

I'm trying to implement a mail-to-fax gateway, and I thought address extensions might help me. If I'm approaching this wrong please correct me. I've already proven to myself that I can define a fax service in master.cf, add a fax transport mapping, and it works great. However, this uses a ho
