It's a scheme whereby the headers get cryptographically signed, as a body, with a key derived from a DNS lookup; another anti-forgery scheme, like SPF, only hopefully more forwarding-friendly. The idea is that relays sign the headers from a given Received: line on down, thus validating the path a mail has taken without breaking the ability for further relays to add Received lines. So adding things above Received lines is safe: adding them below invalidates the DK signature. (Yes, I think it looks ugly, too.) -- `Next: FEMA neglects to take into account the possibility of fire in Old Balsawood Town (currently in its fifth year of drought and home of the General Grant Home for Compulsive Arsonists).' --- James Nicoll
