I tried posting to the list several times now without success. I hope
this this one finally gets through.

Another way to deal with this is sender confirmation by email, where,
like subscriber confirmation by email, a message is sent with a
confirmation link. Mailman doesn't have this capability presently but it
seems to me that since it already has subscriber confirmation, it should
be possible to adapt that sender confirmation.

This sender confirmation by email feature is available in L-Soft's
LISTSERV, and it is an essential way to avoid fake email.

In a post a few years ago Barry said that this feature was going to be
in vers. 2.2, but that version never materialized. Will it be in vers. 3?
