The PG lists do not think so; for example in -hackers traffic you will
find
Sender: pgsql-hackers-ow...@postgresql.org
which matches the envelope From address. Every other mailing list I'm on
behaves similarly. Now, I'm not an email standards guru so I have no idea
whether that's actually necessary or not, but I kinda doubt that you're
right and all the mailing list software authors are wrong.
