This makes procmail deliver mail into mbox format files. You most likely
want delivery action lines like this:
  .probably-spam/

Note the leading dot and the trailing slash. That makes procmail use
Maildir format. You will have to adjust each and every delivery action.
Please see 'man procmailrc'.

Moreover, your ${PROBABLYJUNK} variable doesn't match your ${DEFAULT}.
You'd better not provide absolute, full paths there.


Given the above snippets, I guess procmail actually *did* deliver your
mail. It's just been dumped in mbox format files, which dovecot with
your changed settings doesn't recognize. And probably scattered in
multiple directories...
