Abstract

A content or document management system includes a content or document repository; a dedicated e-mail account; and a mail agent associated with the dedicated e-mail account. The mail agent processes a received e-mail message to determine a sender'"'"'s identity; authenticates the identity of the sender and an authorization of the sender with respect to the content or document repository; parses, when a sender is authenticated and authorized, document request information from the e-mail message; and either stores a document to or retrieves a document from the content or document repository. The mail agent may authenticate the identity of the sender using a digital signature, or may authenticate the identity of the sender using an e-mail address in a FROM header field of the received e-mail message header. The mail agent may decrypt encrypted messages from the sender, and may sign and encrypt responses to the sender.

said mail agent, when a sender is authenticated and authorized, interpreting the name field of the received e-mail message with the attachment to determine the location within said repository for storing the attachment;

said mail agent, when a sender is authenticated and authorized, authorizing the specific request, and forwarding the attachment to said repository, the formal request including identification of the location within said repository for storing the attachment identified by the name field of the received e-mail message with the attachment.

8. The system as claimed in claim 1, wherein said mail agent processing a received e-mail message with an attachment, to determine a sender'"'"'s identity, the received e-mail message with the attachment an alias e-mail address which is associated with an e-mail account of a mail agent of said repository, the alias e-mail address having a local part, the e-mail message having a request to store the attachment in said repository;

said mail agent authenticating the identity of the sender and an authorization of the sender with respect to said repository;

said mail agent, when a sender is authenticated and authorized, interpreting the local part of the alias e-mail address of the received e-mail message with the attachment to determine the location within said repository for storing the attachment;

said mail agent, when a sender is authenticated and authorized, authorizing the specific request, and forwarding the attachment to said repository, the formal request including identification of the location within said repository for storing the attachment identified by the local part of the alias e-mail address of the received e-mail message with the attachment.

9. The system as claimed in claim 1, wherein said mail agent processing a received e-mail message with an attachment, to determine a sender'"'"'s identity, the received e-mail message having a predefined syntax in a body of the received e-mail message, the e-mail message having a request to store the attachment in said repository, the predefined syntax defining location within said repository for storing the attachment;

said mail agent authenticating the identity of the sender and an authorization of the sender with respect to said repository;

said mail agent, when a sender is authenticated and authorized, interpreting the predefined syntax of the received e-mail message with the attachment to determine the location within said repository for storing the attachment;

said mail agent, when a sender is authenticated and authorized, authorizing the specific request, and forwarding the attachment to said repository, the formal request including identification of the location within said repository for storing the attachment identified by the predefined syntax of the received e-mail message with the attachment.

10. A method for managing the distribution of documents in a repository, using a dedicated e-mail account and a mail agent associated with the dedicated e-mail account, comprising:

(a) processing a received e-mail message to determine a sender'"'"'s identity, the received e-mail message having a predefined syntax in a body of the received e-mail message, the e-mail message having a request to retrieve a document from the repository, the predefined syntax defining the document to be retrieved from the repository;

(b) authenticating the identity of the sender and authorizing sender with respect to the repository;

(c) interpreting, when a sender is authenticated and authorized for the repository, the predefined syntax of the e-mail message to determine the specified document within the repository;

(d) authorizing the specific request; and
