[Mimedefang] Letting emails to postmaster through unaltered

Mimedefang Users,

I've added this to the top of filter_begin():

    ## RFC 2821 (section 4.5.1) postmaster should be more liberal and rarely blocked.
    ## For fault diagnosis, I prefer these emails be unfiltered by MIMEDefang
    if (my @postmasters = grep { /postmaster@?/i } @Recipients) {
        if (@postmasters != @Recipients) {
            ## Other recipients, resend email to postmasters only
            foreach (@postmasters) {
                delete_recipient($_);
            }
            resend_message(@postmasters);
        }
    }

And this to the top of filter($$$$):

    ## Accept email only going to postmasters (see filter_begin() comments)
    return action_accept() if 0 == scalar grep { not /postmaster@?/i } @Recipients;

Comments?

Yours sincerely,
