What do you mean by "the spammer is on the list"? The spam messages
don't go via list. I would get them (my own mail server and no spam
filter beyond the standard Exim header checking, which would never
drop/reject a mail coming from the list).

Yes, I rather think they are targetting you. The Debian mailing
list headers seem to me (well placed) spoof.

Yes, that's how it looks to me. Perhaps they're real bounces,
perhaps they're fake. But I'm pretty sure by now that the
Debian-list related headers are plain fake, to nudge people
into "responding to list" and thus spreading the spam even
more. So folks, don't do that. And if you do, at least strongly
snip the original (as Michelle has done, thankfully) and don't
include the whole kaboodle, top-posting style (you don't top-post,
do you ;-)

FWIW, I've sent a test mesage to (some randomly chosen user name)
at one of the servers in list and am awaiting a bounce message.

Let's see...

@Michelle: could you please send me a *complete* bounce message,
headers and all, as it arrives at your place? I still can't figure
out what kind of headers you sent to this list.
