I agree, it's not clear whether this is a sendmail or a Mailman
problem. However, I have never, AFAIK, failed to receive an email
from my provider's domain, unless that email originated from this
specific Mailman list. That seems suspicious, doesn't it? Of course,
I may be missing other emails that I am not aware of. Not getting
something you did not know to expect is not an easy problem to trap.
Since I now know that I am not receiving all emails from this list,
possibly the problem is common but not often detected because the
severity varies, list by list.

My provider has checked Mailman's smtp log. It shows emails were sent
to all subscribers.

I'm not certain, but I think this answers your question: the list
does have digest options available to the users.

I looked, there are no settings for these in Mailman/mm_cfg.py. There
don't appear to be any site-specific settings here.

The provider has given me sendmail logs that I have analyzed. I was
able to identify entries in the sendmail log that correspond with
mailing list transmissions that were not received by the subscriber

I recognize the difficulty of this particular problem.
