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)
