[Mimedefang] Relay_check not working

[Stefano McGhee]

Hello all,
	I'm trying to get relay check working on a new box with more HP
than our existing system.  I'm running MD 2.20, and Sendmail 8.12.6.  I
have placed the following lines in the sendmail init script that also
starts MD:

            daemon $MIMEDEFANG -U defang -r \
             -m $DEFPATH/mdefang-mx.sock \
             -p $DEFPATH/mimedefang.sock $SENDER_CHECK \
             -P $DEFPATH/mimedefang.pid

In mimedefang-filter I have the following:

# Check for various relay denials
sub filter_relay {
    my($hostip, $hostname, $helo) = @_;

    # Can't be "arcweb.com" unless it's one of our IP's.
    if ($helo =~ /mydomain\.com/i) {
        if ($hostip ne "127.0.0.1" and $hostip ne "local.ip.address" and
            $hostip ne "another.local.address") {
            syslog('info', "Host $hostip said HELO $helo");
            return(0, "Go away. You're not me. I'm me.");
        }
    }
    return (1, "OK");
}


When I telnet into port 25 and issue the command HELO mydomain.com or HELO
server12345.mydomain.com, it is very pleased to meet me.  What might be
wrong?

Many thanks,

Stefano
