I'm running MailScanner/sendmail in gateway mode to an Exchange box.  So I
followed the directions here:

http://wiki.mailscanner.info/doku.php?id=documentation:configuration:mta:sendmail:how_to:setup_a_gateway

Added the Exchange box IP into mailertable and then added the domain into
relay-domains.

Is there a better way to configure Mailscanner/sendmail as a gateway to Exchange
so that it rejects at the SMTP stage instead of having a DSN generated?

Thanks.
