	Well, there are several reasons for these mechanisms
	being added to the smtp-server, and none of them prevents
	you from doing similar/same at the router scripts.

	However there are some things you can't do in router...
	- total blockade of some source IP-addresses  (could do it
	  via the TCP-wrapper, though..)
	- instant lightweight rejection responce
	- address format complexity limitation
	  (I mean !%-kludges, and source-routeing)
