Except that qpsmtpd won't continue to play with that server (i.e. every 
subsequent line will be refused).  I'm actually looking at this with 
require_resolvable_fromhost, which actually does (currently) a 
DENY_SOFT, which is even more wrong.

I think what we need is a "three-strikes" meta plugin: if a remote MTA 
has been sent a DENY_SOFT or DENY and continues to attempt the send a 
message (in the former case without issuing an RSET), then we just drop 
them.  I'm not sure how easy that will be to add to the core code (we 
don't really have a true FSM that we could just add that branch).
