I agree that mails are getting bounced/dropped, but I can't begin to
guess why without seeing actual bounce messages and/or logs from the
relay server and/or logs from your local MTA if you use a local MTA
between Mailman and the relay server.

You may need to talk to the operators of the relay. I know you did and
they told you to rate limit your sending, but do they know that is the
problem, or is that a non-response?

If in fact you do have a local MTA which Mailman delivers to and which
then relays to the relay server, you can investigate rate limiting
there as discussed in the FAQ at <http://wiki.list.org/x/j4A9> to
which you have been previously referred.

Let us see some actual bounce messages. We know there are some because
bounce processing is removing subscribers, so what do they look like?

Also, have you followed up on my following suggestion to verify that
all the owner addresses are deliverable. I.e., what happened to the
nearly 3000 notices from BounceRunner that were indicated in the smtp
log you sent me.
