Belatedly, apologies for the recent spam on cxml-devel. My own spam filter caught most of it, so I did not notice what was going on.
Mailman's default setting on common-lisp.net for accept_these_members was to accept mails appearing to come from common-lisp.net members, including junk addresses like BlogBlaster@common-lisp.net.
I have now disabled this mailman option for cxml-devel.
