Abstract: Nested email delivery substitutes a control token into an recipient email address, and uses the result as the username in email to a domain of a secure processing server. At the secure processing server, the recipient email address is extracted, control token identified, and any attachments processed and delivered based on the control token. The secure processing server may be an internet-based secure fax server and attachments processed as native documents for high-resolution, color faxing. Delivery may also be via certified email, or native documents may be processed into workspace storage or through other configured processing. Multiple tokens may be combined to trigger multiple actions.

Abstract: A first enrolled user of a message transmission uses the system to transmit an invitation to a second user, who is not enrolled as a user of the system. The second user uses the invitation to download and install a messaging client onto the second user's local machine automatically. The system generates a unique ID for the second user automatically. The system executes the second user's messaging client and configures the second user's account and messaging client with the second user's unique ID and account information obtained from the second user. The system automatically transmits any message contained within the invitation to the second user upon completion of the previous steps. The system thereby minimizes the number of manual steps that must be performed by the second user to create an account and to configure the second user's messaging client for use with the message transmission system.
