[Mimedefang] MD error

[Jim McCullars]

Hi, I just downloaded and installed MD 2.17 and either there is a problem
with mimedefang.pl or the sample filter_relay for testing the HELO value.
I adapted it for my machine like this:

sub filter_relay {
  my($ip, $name, $helo) = @_;
  if ($helo =~ /info\.uah\.edu/i) {
    if ($ip ne "127.0.0.1" and
        $ip ne "146.229.5.36") {
          return(0, "Go away... $ip is not in uah.edu");
    }
  }
}

and when I tried to send out a message locally, this showed up in syslog:

Aug 13 15:48:30 infotest sendmail[16735]: [ID 801593 mail.info]
g7DKmUmj016735: from=jim, size=79, class=0, nrcpts=1,

When I changed the script to explicitly add the return code of 1 like
this:

sub filter_relay {
  my($ip, $name, $helo) = @_;
  if ($helo =~ /info\.uah\.edu/i) {
    if ($ip ne "127.0.0.1" and
        $ip ne "146.229.5.36") {
          return(0, "Go away... $ip is not in uah.edu");
    }
  }
  return (1);
}

The message got sent and no errors were logged to syslog.
