If you subscribe for them, then you still have to use confirmation, so
you still have made life difficult for them. You might as well just
bulk subscribe them and separately MAIL them a copy of the NEW
IMPROVED welcome message. Those that bounce can easily be removed from
the list, since the bouncing copies do contain specific addresses.
Still, this will not remove those whose email disappears without a
trace. Only user initiated resubscription or owner initiated renewal
with user feedback can hope to clean out the addresses that point to
black holes. Such a mechanism is available in LISTSERV, but not in
Majordomo, I think. I don't know about others. This program, i.e.
one to simulate LISTSERV style renewal confirmation is fairly easy to
write, so let me know if you want one. It helps if you have a mailing
address to spare for just renewal confirmations.
