Some additional help from my side which you can forward to the
concerned staff.(Not sure if this exactly is the case hoping that this
might be the case)

here is the header at my end  http://pastebin.com/Q5Hut1pD
 this is a header which is from mail which came as  response

Gmail signed Jared Norris' mail with DKIM when he sent it; the mailing
list modified the headers (and maybe the body too); gmail got the
message from the mailing list, tried to verify the DKIM signature and
verification failed. Since it's modifying messages, the mailing list
software on ubuntu.com should be configured to strip DKIM signature
headers, and maybe to add their own signature.
