Microsoft is trying to push the Sender ID technology in an effort to globally reduce junk e-mail levels. One of the major obstacles is that this technology needs to be adopted by all the DNS servers providing mail services. The next versions of Microsoft's anti-spam components of Outlook and Exchange will think of any e-mail coming from a source that did not implement Sender ID as suspect. Should you panic? Not yet.
Microsoft, like other anti-spam solution providers use a "points" system. Every e-mail gathers "bad points" according to well known characteristics of junk E-mails, such as bright red colors, use of certain words, and now the absence of a valid Sender ID record.
To make your e-mails less suspect in the eyes of future Exchange and Outlook versions you can use the Sender ID Tool to help create your own Sender ID Record.
