Another option would be to grab one of those zip+4 databases that has
latitude and longitude for each zipcode.  Then you could take the incoming
zipcode and do an only vaguely complex (once you've got the math down)
calculation to determine which email destination is closest to your starting
point.  That said, this really depends on what your server setup is, and it
assumes that you always want to send the email to the closest destination.

HTH,
