The google and yahoo servers are going to obey the rules
and retry after an appropriate interval and deliver
the spam anyway.  You may as well reduce the load and
accept it immediately.

They may or may not also resend from a different box,
doing a round-robin on outbound mail gateways.
Mail (probably) eventually gets delivered when all the boxes (IPs)
are whitelisted.  But it means that legitimate mail
can get overly delayed.  (Dunno who's doing this any more.)
