Discussion

For Exchange to be able to determine whether a given user is allowed to send messages through a connector, it has to be able to validate that a given message actually comes from a user. Since message headers can be faked, Exchange needs to be able to validate that a message was submitted by a given user. To do this, you need to enable SMTP authentication, so that Exchange can track the required message properties from end-to-end throughout the organization.
