If this is what the client wants, See below.

It is redundant to add the same address as both owner and moderator. It
means that most notices will be sent with that address as RCPT twice
which depending on the MTA will at best send it once and at worst send
a duplicate.

This is OK if you want the member to be removed from the list on the
first bounce, but if you want to merely disable delivery while the
list owner decides if the bounce is 'fatal' or not, set this greater
than 0

Actually, with those settings the bouncing subscriber will be removed
and the admins will receive both a disabled and an unsubscribed
notice. The disabled notice will have a copy of the bounce.

>I assume that all 3 admins should receive the bounce?

They should. I don't know why they don't. Are you sure the fake
addresses are not actually deliverable? It is not clear to me whether
you are hosting this web site and Mailman installation or not, but
debugging this further will probably require access to the mail log
and Mailman's logs on the server.
