Thanks for the suggestion, but I don't believe it applies in our case.
There are several hundred subscribers on each list, with over 200
different mail domains (hence many different servers).

A message from a newly added subscriber is accepted, logged in the
archive, and distributed to all the members of the mailing list.

A message from a existing subscriber is accepted, logged in the
archive, confirming that it was seen and processed (at some level)
by Mailman.  The message *is* distributed to the newly added members
of the mailing list.  But it is not distributed to any of the existing

I do not have direct access to the list server system; I am working
through our ISP's support service.  Any suggestions for what I can
tell them to look for, in Mailman log files or queues or other places,
to see why Mailman does not redistribute a message:

    - from an existing subscriber
    - to any existing subscriber

but (as far as we can tell) is working correctly in all other permutations?
