Use With Caution.

Much spam goes out with forged From: addresses, and many sites will report you
to the various blacklists for this sort of "backscatter" spamming.  Some spammer
throws 1000 joe-jobbed spams, you send 1000 confirmation requests, you get your
server blacklisted.

At *best*, the confirmation ends up double-bouncing to the Listserv postmaster.
