Look at the entry in Mailman's smtp log which will tell you how man
total recipients there wore for each sent message.

If you mean Message-Id:, that's in the smtp log entry. If you mean the
MTA's IDs, they would not normally be found anywhere in Mailman's
logs, and there could be more than one for a single post because a
single post may or may not be sent in a single smtp transaction
depending on Mailman settings and number of recipients.

If you want to know what Mailman thinks, if there are no entries in
Mailman's smtp-failure log, the number of recips in the smtp log entry
is the number of recipients given to the MTA. You can believe this
number or not, but I know of no case in which it is wrong.

If you want to know what the MTA did with these recipients and whether
or not it lost any, that is not a Mailman question.
