I found this in the archive.
deliver to other mailbox formats, you'll need to use the "dmail"
program, availible in UW's IMAP repository. It would be invoked from
a user's .procmailrc as:
:0 w
| dmail
or
:0 w
| dmail +folder-name
Doing this for _all_ users is much more tricky; setting DEFAULT won't
work.

I would like to do it for all users via the /etc/procmailrc file. Is
it possible, and if so, how?
