  The best explanation is the one supplied within 'man 5 procmailex' which
I've pasted below for you.

       If  you  are subscribed to several mailinglists and people
       cross-post to some of them, you  usually  receive  several
       duplicate mails (one from every list).  The following sim
       ple recipe eliminates duplicate mails.  It  tells  formail
       to  keep an 8KB cache file in which it will store the Mes
       sage-IDs of the most recent  mails  you  received.   Since
       Message-IDs  are  guaranteed  to  be  unique for every new
       mail, they are ideally suited to weed out duplicate mails.
       Simply put the following recipe at the top of your rcfile,
       and no duplicate mail will get past it.

              :0 Wh: msgid.lock
              | formail -D 8192 msgid.cache
