Re: Returned Mail

Ron Parker asked,

Phil Edwards's solution was to set TMPFILE=/tmp/$USER.$$.procmail
to get a unique name; my inclination was to let procmail pick it out.
I would set WORKSPACE to the path (relative from $MAILDIR or, better yet,
absolute) to a directory and proceed as follows:

 :0
 * conditions for these actions
 {
  # no need for the extra work to get an MH-style numeric folder name
  # no local lockfile needed either
  :0c
  $WORKSPACE/ 

   :0e # in case directory did not exist
   {
    :0chi
    | mkdir $WORKSPACE

    :0
    $WORKSPACE/
   }

  :0chi # text is now stored in $LASTFOLDER
  | perl scriptname $LASTFOLDER

  :0hi
  | rm -f $LASTFOLDER
 }

Better yet, change the perl script to accept the text as standard input 
instead of requiring it in a file.  Then all you'd need is this:

 :0
 * conditions
 | perl scriptname
