We have a client that we resent moved to some new address space (We have had the the space for a couple of years now) However it looks like the mail server for js.pentagon.mil are droping all packet to them. :(
If anyone had some leads on a way to contact them. Please contact me off-list. We did try the number in the whois for the IP. The phone rang and rang. :( Thank you all. Sincerely, Mark Keymer
