That's disappointing, but understandable (not understandable that
they're doing it, understandable that it makes the lists probably not
very useful to me at work).

Yeah, some of the bounces I'm getting back from sending to
$relay at abuse.net for our "you sent us viruses yesterday" report come
back as bounces that were sent to postmaster at their-domain but they
don't have a postmaster account.  Makes me think I ought to just not
accept their email at all.

Thanks to both of you for your responses.
