xing.com signs the X-Virus-* headers, too. Those tend to be overwritten by any spam- or viruscheckers on the way. I had a conversation with them, they think that this is a great idea because it prooves their checks are trustworthy or so. My hint to rfc and best practices were considered unqualified. Maybe somebody else with higher diplomatic skills wants to talk to them on this matter. Bye, Joerg
