Dave and Craig,
Um, this article is a bit under cooked.
Mail servers have been required since 1986 to look for MX records
(this
is not new) and have been required since 1986 to look for an A record
if MX doesn't exist.
...
Well, then, where is the fema.gov mail server? Attempts to connect to
ns2.fema.gov were successful, ...
A debate about A vs. MX DNS records and requirements is important for
telling admins what they should/must do.
In terms of the salient issue for IP, the discussion on the nanog
(operations) mailing list about this made a very basic, very simple
point quite clear:
FEMA advertises email addresses that do not work, and the
nature of the problem appears to be quite deep in their
network administration.
Further they are apparently unresponsive to operations problem
reports.
Since FEMA is tasked with operations-related activities in a time of
crisis, this failure of such a basic communication just adds to the
frustrations with the organization.
One of the guys who wrote specs that made Craig's work necessary...
