These messages aren't going to the list, they're going to anyone that posts
to the list (i.e. ta-meyer at ihug.co.nz gets the messages when I post with
that address, not all of the spambayes at python.org recipients). I don't know
whether mail.python.org is getting bounces or not - I presume not, or
mailman would be doing something about it.

This (and VERP) was the clue I needed, though (thanks!). The (relevant)
headers of the attached (bounced) messages are (for one such message):
To: "'blakemail at gmx.net'" <"blakemail at gmx.net"@smtp.hispeed.ch>,
<spambayes at python.org>
X-MDRcpt-To: werner at wekorpershoek.nl
X-MDaemon-Deliver-To: w.korpershoek at fresq.nl
So this means that the problem address is "blakemail at gmx.net", right?
That address *is* subscribed to the list.
Could someone that understands this better than me confirm this? If so,
then unsubscribing that address is ok, right? (I presume that attempting to
email either the fresq.nl or gmx.net address would be futile).
