forcing procmail use MBX format (fwd)

Hello,

could somebody tell me how can I make procmail deliver
mails to my INBOX, which is in MBX format ?

Temporarily, I have added the following entry at the
end of procmail.rc file:

:0:
* .*
| /usr/lib/tmail -d zelazo

which catches every message that remains unfiltered
and delivers it to INBOX in MBX format through tmail
mailer.

But I think there is a way to force procmail itself
to write in MBX format.

Thanks in advance for reply,
Robert Zelazo
