Depending on various settings, Mailman may be sending to multiple
recipients in one SMTP transaction and your MTA may only list one of
these recipients along with the Message-ID.

You need to query your MTA logs for the recipient addresses you are
concerned about and see if those are logged as sent or not. If they are
logged as sent, they may still be bounced by a remote MTA in which case,
that bounce will have a completely different Message-ID, or they may be
discarded by a receiving MTA or diverted to a spam folder.

Other than the advice in the FAQ at <http://wiki.list.org/x/4oA9>, all
you can do is provide the intended recipient with your MTA's 'sent' log
message, and the recipient can inquire of her ISP why she didn't receive
the message.
