EXPLANATION:
Reverse DNS lookup for your IP address is failing. AOL does require that all
connecting Mail Transfer Agents have established reverse DNS.
SOLUTION:
Reverse DNS is a way of associating an IP address with its domain name. The
reverse DNS identifier is contained in the PTR portion of the IP Zone File.
You may look at your reverse DNS using our
reverse DNS search tool.
If you are on a dynamic IP address, please call your ISP and request a
static IP address with proper rDNS before attempting to send mail to AOL
through that server.
If you are on a static IP address, please call your ISP or DNS provider and
ask them to
establish a reverse DNS record for your IP address, reflecting your correct
domain name.
