Fighting Spam with procmail

[Lukas Ruf <ruf@rawip.org>]

Dear all,

is there an easy way to pass an email message again through a
procmail such that particularly created rules can be verified easily?

I read sth about formail/procmail, however, have not yet seen the
right way to do.  From man formail:

    formail +1 -ds procmail

What I would like to do was sth like:

    cat msg.mbox | procmail procmail_test_rc

Where msg.mbox contains all the emails, I would like to filter again,
and procmail_test_rc contains the rules to be tested.

Thanks for any hint!

wbr,
Lukas
