[Mimedefang] md_check_against_smtp_server

[Bill Maidment]

Hi

I'm trying to use md_check_against_smtp_server to check the email 
recipient against valid users on another mail server.

The problem I have is that invalid recipients cause the incoming email 
to continually bounce between my two mail servers. Valid recipients work 
fine!

Any clues as to what I've missed/got wrong?

I have this in sendmail.mc on the other mail server. Could this be the 
cause?

define(`SMART_HOST',`mail.maidment.com.au')


mimedefang-filter snippet and email sample follow:

#***********************************************************************
 

sub filter_recipient ($$$$$$$$$) {
         my($recip, $sender, $ip, $host, $first, $helo,
                 $rcpt_mailer, $rcpt_host, $rcpt_addr) = @_;
         return md_check_against_smtp_server($sender, $recip,
                 "mail.maidment.com.au",
                 "video.maidment.com.au");
}
