If the files you diffed contained All the Received: headers, this might
indicat the the duplication is occurring after final smtp delivery to
her, perhaps by message rules, but that would not explain why the
number goes from 3 to 2 when you suspend delivery.

That complicates things. You may need to enlist help from dreamhost.

Mass unsubscribe doesn't accept patterns.

Unless dreamhost is using a non-standard member adaptor in their
Mailman (I think they have a standard Mailman 2.1.9 with htdig
your speculation is not possible. The member database is a Python
dictionary keyed by lower-case email address. It is not possible to
have duplicate keys in a Python dictionary, thus it is not possible to
have two entries with the same email address.

Do these original messages contain all the Received: headers?

The change in boundaries indicates that these messages were 'remailed'
which in turn indicates that you may not have all the original
headers. You need to get the entire raw message source for these
messages from Viv. How she gets this depends on her MUA.
Here are some other things you can try:
On the Membership list page, enter some pattern in the 'Find member'
box that will match for sure all of her possible addresses and as few
others as possible - maybe her username or part of the domain. The
idea is to get one page of results with just a few entries so you can
see the table and the 'n members total' heading. See if the number of
entries in the table is fewer than n from 'n members total'. If so,
look at the raw html source and see if you see anything.
If you have a 'personalize' setting on your Non-digest options page,
set it to 'Yes' and add the line
This message sent to %(user_delivered_to)s.
to msg_footer. If there really are three messages being sent, this
should be different in the three messages received.
Other things will require dreamhost cooperation.
