Oh, hogwash.

Years ago (1995 timeframe), I was able to do a million RCPT TO's/day from a
listserv machine, using Sendmail on an IBM RS6000-250.  Little pizza box, 256M
of memory, a whole whopping 66mz 601E processor.  If spammers can't write code
tight enough to do so un-noticed on today's consumer boxes, there's something
*seriously* wrong.
