You have to work with your ISP to send SMTP mail to your Exchange server. To send mail, create an SMTP Connector with address space *. Either configure your ISP's SMTP server to be your smart host, or don't, depending on whether your ISP requires it. Be sure that you have a recipient policy containing your SMTP domain, and recipients have SMTP addresses for which they will receive mail.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."
