[Mimedefang] bounce check with sendmail and md_check_against

[Wayne]

I do realize that it is open but I restrict that on the server. Here is my 
filter_recipient.
#*************************************************************************
# %PROCEDURE: filter_recipient
#
sub filter_recipient
{
    connect_to_database();
    my($recip, $sender, $ip, $host, $first, $helo, $rcpt_mailer, $rcpt_host, 
$rcpt_addr) = @_;
        my $from_name;
        my $from_domain;
        my $relayflag = 0; # set the relay flag to 0 then check the hostname 
and use it later for delay

        if (($host !~ /\.(?:com|net|edu|org|gov|mil|ca|ne.us)$/) ||
               ($host =~/\d{1,3}-\d{1,3}-\d{1,3}/) ||
               ($host =~ /\d{1,3}\.\d{1,3}\.\d{1,3}\..*/) ||
               ($host =~ /dial|client|dhcp|dynamic|\.dyn\./) ||
        {
         $relayflag = 1;
        }

        if ($recip =~ /bwtelcom/i){
         ($result, $rmesg)= md_check_against_smtp_server($sender, 
$recip,"smtp1.hamilton.net","mail.bwtelcom.net");
         }
         else{
         ($result, $rmesg)= md_check_against_smtp_server($sender, 
$recip,"smtp1.hamilton.net","mail.hamilton.net");
         }

        if($result =~ /CONTINUE/){
        return ('CONTINUE' ,"ok");
        }
        elsif($result =~ /TEMPFAIL/){
        return ('TEMPFAIL' ,"$rmesg");
        }
        else
        {
        if ( $relayflag ){
                           return ('REJECT', "unknown user account", "550", 
"5.1.1", "10");
                          }
        else{
             return('REJECT',"unknown user account", "550", "5.1.1", "3");
             }

}
