   This is what I did in filter_begin:

    if(open(HDR, "<HEADERS")) {
      while (<HDR>) {
        if(/^X-MailScanner.+clean/) {
          close(HDR);
          return action_bounce("This email exhibits characteristics of the SoBig virus - rejected");
        }
      }
      close(HDR);
    }

   HTH...
