Re: nan in bogofilter stats

Here is the code snippet from my amavisd.
As you can see, I do the return value processing "manually". The config file 
forces a two-state return.

Cheers,
Stephen

# run bogofilter against previously collected email body
# #
#
  my($fname) = $msginfo->mail_text_fn;
  chop($output=`/usr/bin/bogofilter -v -I $fname 2>&1`);
  my($errval) = $? >> 8;
  do_log(1,"Bogofilter gave " . $output);
  if (! $errval){
    system("/usr/bin/bogofilter -s -I $fname");
    $errval = $? >> 8;
    if (! $errval){
      do_log(0,"Spam registered.");
    }
    $msginfo->spam_level(10);
    $msginfo->spam_status("bogofilter");
    $msginfo->spam_report("Spam found");
    (10, "bogofilter", "Spam found");
  } elsif ($errval == 1){
    system("/usr/bin/bogofilter -n -I $fname");
    $errval = $? >> 8;
    if (! $errval){
      do_log(0,"Ham registered.");
    }
    $msginfo->spam_level(0);
    (0);
  }
