Look to see if they have a "Sender:" header.  Netscrape Mail, and probably
some other programs written by people with only a passing familiarity with
RFCs, inserts an invalid "Sender:" header a lot of the time.  Since this
Sender disagrees with the address of the person on the list, mailman puts the
message aside for manual approval.

It's a pain in the ass.  If the person *is* using Netscape under Unix or
Linux, tell them to exit Netscape, and put the following in

user_pref("mail.suppress_sender_header", true);
