I had Relaying not allowed on my Exchange 2k Server and this broke one of our web apps that sends out email invitations to meetings hosted by our web server. I put to allow relaying from that web server in my SMTP connector. Now the invitations can go out but I was wondering if there is a way to restrict it so that I can only go out if they have our domain in them. In other words only relay from that server if it has *@mycompany.com as the email address. As it stands right now any domain from that server can relay email out. Steve
