	Contrariwise, being the original Senior Internet Mail Systems 
Administrator for AOL, and one of the originators of many of the 
early anti-spam techniques, I consider it to be one of the most 
effective (and simple) measures available.

	There is no way I would even consider setting up a mail server 
without turning on this feature -- certainly, I wouldn't do so except 
under extreme pressure, and even then I would only do so under 
violent protest.

	Right, well I don't use .rhosts or hosts.equiv at all.  If you 
want onto my machines, you have to have your ssh key in the 
appropriate file, otherwise you don't get through at all.
