OK, but normally the rDNS PTR is the reverse of the regular IP.  In the example,
the IP 10.99.0.1, but the wiki example PTR has only 0.99.10 and leaves off the
'1' from the final octet.

For example, my IP is 24.142.169.12. If I look that up I get:

# host 24.142.169.12
12.169.142.24.in-addr.arpa domain name pointer novatec-inc.com

All 4 octets shown. If I just try with the top 3 octets I get:

# host 24.142.169
Host 24.142.169 not found: 3(NXDOMAIN)

Maybe this is something special for the DC, but I've always seen and used
all 4
ipv4 octets in rDNS PTR records.

Just checking ...

I am getting both your messages. Don't know why your getting some indicator
that
you need to resend.
