No, it is not a bug in Mailman and it probably will be no different
under Mailman 3.

You have to follow the mail through the various MTAs between your
Mailman server and the recipient server.

Typically, you or your service provider will find a log message
indicating the original email message was accepted for delivery by the
recipient's ISP, but the recipient never gets the mail. At this point,
All you can do is provide the recipient with the full log message
containing timestamp and the receiving server's queue ID, and then the
recipient has to take this up with their ISP.
