The latter uses a lockfile, which ensures that the mailbox won't be
written while the recipe is executing (at least not by procmail).

For mboxes, you want to use a lockfile, for maildirs you don't (well,
you could use them on maildirs, but they'll just slow things down a

These sections from procmailrc(1) may now be clearer:

       A line starting with ’:’ marks the beginning of a recipe.  It
       has the following format:

              :0 [flags] [ : [locallockfile] ]
              <zero or more conditions (one per line)>
              <exactly one action line>


   Local lockfile
       If  you put a second (trailing) ’:’ on the first recipe line,
       then procmail will use a locallockfile (for this recipe only).
       You can optionally specify the locallockfile to use; if you
       don’t however, procmail will use the destination filename (or
       the filename following the first ’>>’)  and  will  append
       $LOCKEXT to it.

I expected times like this -- but never thought they'd be so bad, so
long, and so frequent.
