Various embodiments are generally directed to techniques and apparatuses to facilitate message communication between registered entities of an email system and other non-registered entities. In one embodiment, a transport component executes on a logic circuit to receive a request to perform a function on an encrypted message. Information embedded in the request is identified to determine if the original request was sent by a registered entity. The embedded information is authenticated with information contained in an authentication information store associated with the original request and if the information is authenticated, the requested function is executed. In addition, if the requested function by the non-registered entity is to send an email message, rich scanning is performed on the email message to ensure the safety thereof.
