This is well and good until enough sites do it to force the spammers
to adapt.  The next generation of botnet spam mailers will just have
to open a large number of SMTP connections simultaneously and pay
attention to protocol niceties in order to maintain throughput.

Just another turn of the spiral in the war between spammers and the
rest of us, I'm afraid.

Someone please tell me I'm wrong.
