Computerized method and system for managing an email input facility in a networked secure collaborative exchange environment

A method for managing a networked secure collaborative computer data exchange environment, the method comprising:

• establishing, by a secure exchange server controlled by an intermediate business entity, a client login data authentication procedure that allows at least one client computing device of a plurality of client computing devices operated by users of a plurality of business entities to access the secure exchange server, wherein communications between the secure exchange server and the plurality of client computing devices is through a communications network;
• storing, by the secure exchange server, at least one client login authentication data for each of the plurality of client computing devices;
• receiving content from a first of the plurality of client computing devices operated by a user of a first business entity of the plurality of business entities;
• by the secure exchange server, permitting access to the received content for a subset of the plurality of computing devices through an exchange content access facility, wherein the exchange content access facility is managed by at least one business entity of the plurality of business entities;
• granting, by the exchange server, access to the received content to a second of the plurality of client computing devices operated by a user of a second business entity of the plurality of business entity when the secure exchange server receives from the second of the plurality of client computing devices its client login authentication data provided that the second of the plurality of client computing devices is one of the subset of the plurality of computing devices;
• and
• providing a secure email input facility for accepting non-secure email from outside the exchange into the secure collaborative computer data exchange environment, wherein the non-secure email is received and at least one of the non-secure email and the content delivered thereby is stored as secure content in a location of the secure exchange server related to at least one of the sender of the email, the subject line of the non-secure email, the destination address of the email within the exchange, and the content of the email.
