I'm not sure if it's the same deal, but The "Liferaft" list at
tmonroe.com (ezmlm) also behaves like this. Your subscription is
based on your envelope From_ not your From:.

When you send a message from your PC with DOS, the envelope From_
and From: are probably the same. When you send a message from PINE
on your shell account, the system writes the envelope From_. The
only way I know how to change that is to do something like:
$sendmail -t -f [EMAIL PROTECTED] < message.txt (I'm not sure about all
the switches).

On the Liferaft list you can "allow subscribe" (or something like
that) another address which allows you to post with it without
also receiving the list at that address.

I don't know about the Nettamer list, but with other lists I see
the envelope From_ of the list, not the poster. With the Liferaft
list I can put any address I want in the From:.

I think the first order of business is to learn how to use both
types of list.

P.S. I have given Clarence my email address, so I may not be on this
list much longer.
