I want to set up a Receive Connector with Exchange2007 for POP email clients to use as an SMTP server.
I want anyone to be able to use this connector even though they will not be an exchange user or have their domain hosted on the server.
To keep the connector from being an open relay I want to set up a user in Active Directory to be used for authentication purposes.
If this is possible your insight would be appreciated. Thank you for taking the time to read this.
