stating: "The e-mail account does not exist at the
organization this message was sent to. Check the
e-mail address, or contact the recipient directly to
find out the correct address."

This doesn't come from Mailman. It comes from the MTA.
Unless the MTA is actually checking list membership before
accepting posts, the poster sent the post to the wrong address.

1- delete all users
2- change the Membership Management/Additional Member
tasks/Set everyones moderation from No to On
</quote>

Which does absolutely nothing at this point besause there
are no members to set to 'moderated'.

<quote>
3- Add all of the users
4- attempt a post from a user
> this produces the correct behavior, an email is sent
to the member stating "hey Im holding this until
approved" AND the moderator gets an email "do you want
to approve this".
</quote>

And how did steps 1 - 4 produce a moderated member?

<quote>
So the bug is that changing the users moderation flag
from off to on is NOT the same as subscribing a user
with the "Action to take when a moderated member posts
to the list" set on.

I don't see how the above statement follows from your tests,
notwithstanding the fact that it is an apples/oranges type
of statement. I.e., the moderation flag and the action are
not an either/or situation. They are two independent
settings that work in concert.
