Either Ultradns is Andrey's mail server, or he appears to have left out his perimeter's Received line. More likely the latter. Without seeing the final received line, can't tell whether this really went thru UltraDNS. Many BOTS forge headers. It's not at all unusual to see: Received: from a by b (b is my server) Received: from c by d where d != a. Meaning the second Received line is entirely fabricated.
