We've had some of these Undetermined origin things here too, on a
list gated to a newsgroup.

My guess is that this came over from the Usenet side of your gated
list/newsgroup.  It looks pretty similar to one of today's cancels
listed in the news.admin.net-abuse.bulletins newsgroup.

Actually owner-listserv is the postmaster (which may also be you, of
course...).  I remember thinking that was an interesting choice for a
default when it happened here.  But on the other hand, presumably a
posting that was actually from the postmaster would use his/her
regular email address, so perhaps the "owner-listserv" address could
be put in a filter.  Does anybody know if this works and is safe?
Would it ever stop anything besides the "Undetermined origin" stuff?
