I suspect that Mailman's logs will not point to the root cause, because
I suspect this problem is outbound from Mailman. I may be wrong about
this, but whether or not it's Mailman's problem, Mailman's smtp log
will verify whether or not the posts are being sent from Mailman to
the expected number of recipients in each case.

Your ISP's tech support should first use Mailman's smtp log to see
whether or not it is Mailman dropping recipients. If it is Mailman,
then cPanel is the correct place to go. If not, then start looking at
the outgoing MTA's logs to see what happens after Mailman.
