My original point is the RBLs that block properly set-up mail servers that 
have never sent any SPAM, just because they're from a range of addresses 
that someone has decided are 'not proper' is a much greater perversion (if 
not violation) of the RFC.  Yes greylisting is a perversion and I wouldn't 
recommend it for high volume applications, but it works for me (tm) :-)

Maybe it comes down to RBLs are useful if used intelligently (qv Donald 
Gordon's earlier post), and greylisting is useful if set-up properly (I'll 
go and review my setup :-).
