Re: Dupe filter with store.

Mike Harris asked,

| I would like a dupe filter that saves the dupes into a folder

| I'd like it to store the dupes into a folder if possible.

As Era Eriksson has posted, more recent editions of the procmailex(5) man
page offer something like this:

      :0Whc:msgid.lock
      | formail -D 8192 msgid.cache
       :0a:
       dupes

This is equivalent:

      LOCKFILE=msgid.lock

      :0:
      * H ?? ? formail -D 8192 msgid.cache
      dupes

      LOCKFILE
