That's OK, there are plenty of systems that don't forward mail across
advertised mail paths either.  I find reliability of paths in this order,
roughly:

	personal knowledge			(most reliable)
	signature lines 
	domain From: addresses in mail headers
	news paths
	From_ lines in mail headers
	advertised mail paths in map entries
	domain From: addresses in news headers
	uucp From: addresses in mail headers
	mixed From: addresses in mail headers	(least reliable)
