Er, I think you're getting your terminology mixed up. Those are usually
considered to be the same thing (ie, the SMTP "MAIL FROM:" == envelope
sender). I think you mean the "From:" field in the message headers
instead of "envelope from".

The "From:" header, not the envelope sender. Any message sent to the
list should show up in your inbox with the sender's address as the
"From:" address (displayed by your mail client), and the listadmin
address ([EMAIL PROTECTED] for this list IIRC) as the
SMTP envelope sender.

This is how SOME lists are configured; this is not how all mailing
lists work. Reply-To munging is a Holy War; IIRC it was debated here a
while ago. I specifically set my Reply-To to point to the list here,
because it's rare that anything I post has any reason to get a private
reply.

All decently-written mailing list software I know of will send mail as a
specific envelope sender ("rewriting" it from the original sender's
address) so that bounces don't spam the original sender. There have
been a few misbehaved vacation programs used by people on this list, and
a few rather strange postmaster notices I've seen in reply to messages I
sent to the list (which should have gone, quite properly, to the list
manager address rather than to me personally). The only case where I
should see a bounce for a mailing list message is if the list server
itself rejects my message for some reason.

Lists like this are pretty tame; most list-archive software I've seen
in the past 4-5 years or so will happily blank out or otherwise
obfuscate most email addresses (some ignore the body; some don't).
Scraping mailing list archives is a pretty time-consuming way to get
email addresses- if any. Websites and Usenet are far easier.

Er... You don't want mail that you send to the list to appear as if you
wrote it? That's what you're asking for here...
