Yeah, that was my first suspicion and it really fit all the way up
to the fact that two of them were actually pretty good posts that
sparked useful and deep running threads, and the third was
non-commital to the point of being ho-hum (technically on-topic,
simply re-iterated prior traffic).


The members and I in each case just agreed to >boggle< and keep
running without comment, under the suspicion that comment would only
encourage the activity.

Problem is, I know how trivially simple it is:

  $ dig python.org MX
  python.org.             23h47m13s IN MX  50 dinsdale.python.org.
  $ telnet dinsdale.python.org smtp
  HELO kanga.nu
  MAIL FROM: <insert member address here>
  RCPT TO: mailman-developers@python.org

(which in one case appears to be exactly what happened)
