[wplug] Unable to post to AOL list

Okay, our IT guy come up with the following, basically this vario is the 
enity that owns the IP's that verizon is leasing to us through our ASDL 
hookup.  Even though a forward lookup of our IP address will tell you 
who we are, (by our DNS -- and be vouch by verisign), the reverse lookup 
is handled by vario's DNS and they could care less about who we are.  I 
guess my work around is to subscribe a personal email acount, and then 
use web based email from work to post to the aol list.

Thanks all.
Reverse DNS for 207.206.8.226


          Generated by www.DNSstuff.com <http://www.DNSstuff.com>

*Preparation*:
The  reverse DNS entry for an IP is found by reversing the IP, adding it to "in-addr.arpa", and looking up the PTR record.
So, the reverse DNS entry for 207.206.8.226 is found by looking up the PTR record for
 226.8.206.207.in-addr.arpa.
All DNS requests start by asking the root servers, and they let us know what to do next.
See How Reverse DNS Lookups Work <http://www.dnsstuff.com/info/revdns.htm> for more information.

*Answer*:
*No PTR records exist for 207.206.8.226.* [Neg TTL=86400 seconds]

*Details*:
b.ns.verio.net. (an authoritative nameserver for 8.206.207.in-addr.arpa., which is in charge of the reverse DNS for 207.206.8.226)
says that there are no PTR records for 207.206.8.226.

To get reverse DNS set up for 207.206.8.226, you need to speak to your Internet provider.  You could also
check with dns at verio.net., who is in charge of the 8.206.207.in-addr.arpa. zone.

Note that all Internet accessible hosts are expected to have a reverse DNS entry (per RFC1912 2.1),
and many mailservers (such as AOL) will likely block E-mail from mailservers with no reverse DNS entry.
