I fail to see any way in which this adds legitimacy, as long as the rDNS 
is legitimate. And in the case of my non-profit discussion and 
announcement server, from which we deliver on behalf of 80+ 
organizations, the cost of 80+ IP addresses, and the need to support 80+ 
virtual interfaces (and throttle simultaneous sending behavior on them) 
would probably put us under.
