In my experience, all Swen stuff comes with genuine envelope sender.
Being a modem user and with a mail volume that's easy to manage, that's
how I'm blocking it - I block off 95% of TLD envelope sender domains to
begin with and make exceptions for the goodies. You'd be surprised at
how many TLDs there are. I just allowed through 71 genuine mails and
rejected 327 that way, amavisd-new dealt with 12 .exes that slipped
through (just costs me extra connection time). Not one made it through
to me. In this respect, pflogsumm is a true blessing; renewed thanks
from a grateful user ;)

Right. They're all getting "Access denied" from me, but looking at some
of the luser addresses, I doubt whether they'll understand. "I never
sent him any mail, I don't even know him, forget it". Though if enough
people are doing it, i suppose the penny might drop.
