Microsoft Phishing Filter Error

Return Path is reporting on the following error made by Microsofts anti-phishing filters:

On Monday some messages sent to Hotmail users were being routed to the junk folder with the Warning: this message may be a phishing scam. The reported error resides with the Microsoft phishing filter that had flagged a very common link in many HTML messages, specifically the link http://www.w3.org/1999/xhtml.

The Microsoft team has adjusted the phishing filters and assures senders that the issue has now been resolved and that no actions need to taken.
