[LDM #NJW-181488]: Fwd: ldmd.conf allow statements

Michael,

I drove your inquiry into our tracking system so that others can see your
very good general question.

The above is unnecessary *only if* the IP address *always resolves* to a host
in the domain crh.noaa.gov. If your DNS resolver goes out-to-lunch, then
that host won't be able to connect. So, it depends on the confidence you 
have in your DNS.

> allow    ANY     ^ftp-210\.crh\.noaa\.gov$

This one is definitely unnecessary: this particular host is covered by the
ALLOW for the domain.

Regards,
Steve Emmerson
