Here actually, since this is the affected list.

If the list server would just delete email addresses then most
of the problems would stop within a few months I think.

Email addresses can be replaced be u_s_e_r_@_i_s_p_._c_o_m if
they are being collected mechanically from the news feed.

If there is a chance someone might code something to fix
addresses like that, then we can substitute 25sep96.42@some.place.
That some place may not exist (spammer bounces _lots_ of mail
because all the addresses are unique).

Better yet, some.place can forward mail to the real user for 48 hours
after a post, send a polite note for the next 7 days, and send the
source tree after that. The remailer can log hosts that seem to send
a large amount of mail to the fake addresses.
