Corporate XMas eCards

eMail traffic swells during the festive season to transport all the eCards. Since it is quite difficult to distinguish between true greetings and all sorts of maleware I usually don't bother to open them. Today one arrived from a very big consultancy with the familiar " .nsf/0/" inside the URL. So I curiously had a look. Seems like they encourage their staff to use the facility instead of moving to a less trustworthy external service. Nice move, now I need to educate them how to secure such an application!
