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,
