Web admin, General options.

It is normal if the total number of addresses in the 'owner' and
'moderator' lists is two.

The owner notice and the user notice are different messages with
different Message-IDs.

Note that some notifications such as held message notifications are
sent twice and have two smtp log entries. The first send has one
recipient which is the list's -owner address, and this is followed by
the resend to the owners and moderators. This is not the case for
(un)subscribe notices however. Subscribe and unsubscribe owner notices
are sent directly to the owners and moderators without going through
the -owner address.
