RE: IIS, SMTP, and DNS resolution



To route mail to a particular host for a particular domian you can try using
smart host configuration instead of DNS. Configure the smathost pointing to
internal IP address of the destination domain's SMTP server. This has to be
done on your SMTP server

Hope this helps..
