The simplest way to keep a copy is just to add a file to the alias entry 
when you create the list, e.g.

  mylist: /var/spool/lists/mylist,"|/home/mailman2/mail/wrapper post mylist"

Even better would be to keep a big "Received Chronicle":

  mylist: "|/usr/local/bin/reformail -c -X Message-Id: -X Received: |sort 
>>/var/spool/lists/mylist_recvd","|/usr/local/bin/reformail -I Received: | 
/home/mailman2/mail/wrapper post mylist"

That file would contain just the message ID's (or you could use From:) 
followed by their Received: lines.  Tracking down a problem would be 
relatively easy.

You can use one of the log rotater programs to swap these out when they get 
too big.
