Sometimes you can't. There is plenty of broken mail software that sends
the mail back to the From: header instead of the envelope sender (which
Majordomo sets to email@example.com). There simply isn't anything
you can do about it. Helpful list members will simply forward one of the
bounces to you and you can terminate the bad address with extreme prejudice
and be happy that the bounces didn't go to your list instead.
