Interesting new twist in the industry as a result of a US patent acquired by Postini. The patent effectively says that any system which intercepts mail, filtering viruses and spam messages from the inbox and then sends what's left to the intended recipient is using Postini's intellectual property (IP). This could apply to a large section of the anti-spam and anti-virus market. Postini's patent describes using a modified DNS address to redirect email to an email pre-processing service which can "detect and detain unwanted messages such as spam, viruses or other junk email messages". It covers various actions that could be performed on an incoming message, based on a user's settings. These include deletion, forwarding, forwarding of partial messages and mailing to several addresses. It also covers broadcasting the message to one or more wireless devices.
