The claimed subject matter provides systems and/or methods that facilitate interpreting Multipurpose Internet Mail Extensions (MIME) data. An interface can obtain MIME data. For instance, a stream of MIME data can be obtained, MIME data can be loaded from a static file, etc. Moreover, any disparate type of RFC 822 data can additionally or alternatively be received by the interface. Also, a MIME reader can analyze the MIME data (and/or normalized RFC 822 data) to interpret encoded structural information and generate at least one primitive based on the encoded structural information. Further, a hierarchical model can be built utilizing the at least one primitive.

Document object model API for MIME

A MIME or XML formatted message is stored and a map is processed in place of a message. The map is a compact representation of the message. The map is indicative of the content and structure of the message. The map comprises tags that map to and are indicative of portions of the message. When a portion of the message is to be accessed, the associated tag in the map is processed to determine the location of the associated portion of the message, and the associated portion of the message is accessed at the location. To allow accurate decryption of signed messages, the format of the message is preserved.

Formatted message processing utilizing a message map

Disclosed is a policy based method for blocking the automatic dereferencing of web beacon links in an e-mail message sent in HTML format with a minimum sacrifice in the HTML body rendering quality. HTML content that potentially contains web beacons is replaced with non-dereferencing elements prior to HTML rendering by the e-mail browser so that the remaining HTML can be rendered as complete as possible without rendering the potential web beacons. Additionally, the present invention also provides a method for removing the HTTP Referer header from referenced external links and activated images. An HTTP redirector service is implemented as a server-based link redirection evaluator application which serves to eliminate the Referer header for the URL requested. Embodiments of the present invention provide for blocking web beacons and removing HTTP Referer headers in both a 'down-level' e-mail client and a client which can make programmatic use of an HTML rendering engine.
