I had the same problem some time ago. My solution was to use a small
perl script to read the mbox file and pipe each message into procmail.
I used a simple (dump) rule to save a mailing list into a seperate
mbox file. I append the perl script and procmailrc file at the end as
an example.

Totally agreed.

==> x.doit <==
#
# Usage: perl x.doit mbox1 mbox2 ...
# the filtered output is written to x.box (see x.procmailrc)
# 
$i=0;
#$cmd = "cat -n";
$cmd = "procmail $ENV{PWD}/x.procmailrc";

while ($line = <ARGV>) {
        if ($line =~ /^From /) {
                close OUT if $i;
                $i++;
                #print "*" x 80, "\n";
                print sprintf("mail # %d\n",$i);
                open OUT, "| $cmd";
        }

        print OUT $line;
}
