Good enough for me. It is said that to avoid a bear, you don't
need to be faster than the bear, just faster than someone else
in your group ;)

Who knows. I suspect it would be a *vastly* long time before the
ratio of 'blocked mailing list' to 'personal email addresses' becomes
so high that spammers will special-case their code just to target
mailing lists. Today mailing lists are accidental inclusions on spammer
master target lists. They already deal with email addresses that get
stale and bounce, the trick is to convince them our mailing list address
is similarly 'stale'. This *is* social engineering, by us, of them,
using technology.
