yes, but the problem could also be due to DNS spoofing or some hijacking
technique used on the server that one is talking to via curl, i.e. it's

which is annoying. people are fickle, you'd rather they didn't skip
past your questions.
we use Reply-All because hitting Reply doesn't reply to the list but
to the OP ... and discussions should generally stay on the list.
it basically comes down to 'just live with it', the spam that is,
and make sure you have some decent filtering in place.
