   More and more, I'm seeing UUCP mail going through my host of the format:
	   uucp1!uucp2!uucp3!domain.name!user
   Since we have both Internet and UUCP connections, what's the best way to 
   handle this situtation if your host is capable of sending mail directly to 
   'domain.name'?  Or should it be done?
