I suggest you encourage your client to move to a hosting service that
offers useable mailman lists. There are such services. At least one
(emwd.com) is an active participant in this list.

Since you read the cPanel FAQ, I hope you realize that any or all of
the following may be wrong, but it is correct for Mailman as
distributed by the GNU Mailman project.
What doesn't exist? Mailman mails are from
listname-bounces at example.com. This should be a valid, deliverable
address or bounce processing won't work.

Depending on the actual SMTP response, Mailman may put the message with
undelivered recipients in the 'retry' queue and continue to retry at
intervals (default 15 min) for (default) 5 days. So if the MTA rejects
the 'extra' recipients with a response of 552 or any 4yz, the failed
recipients will be retried. It will still take 5+ hours to deliver to
551 recipients, which implies a hopeless backlog if there are more
than 4 posts in a day, but the mail should eventually be delivered.
It is apparent that GKG is not interested in providing a useable
Mailman service for other than very small, low traffic lists. If they
were, they could accommodate this. Encourage your client to find an
