To require SMTP authentication on an Exchange 5.5 server:

To require authentication for inbound connections:

1. Click the Connections page.
2. In the "Accept Connections" Section, mark the radio button for "Only from
hosts using Authentication."

But beware, if you have a server that is accessible from the internet, most mail will be bounced back. Because most of the SMTP servers on the Internet
only support Anonymous Authentication, inbound sessions from external SMTP servers will be affected. Only use this if you control the other end of the SMTP connection.

Go to the properties of the Internet Mail Service. Go to the Security tab.
Under E-Mail Domain, you should have a entry of "<Default>, highlight it and click edit. Under "Outbound connections" select the authentication type you
want to use, most likely it will be the last bullet "Windows NT challenge/response authentication and encryption". When you select that
click change to and enter the account information.
