This form is to request reverse DNS to be setup on your BT hosted IP address. Only attempt this if you have experience in setting up mail servers.
If you are running your own local mail server you may encounter problems sending emails through some spam filtering systems because of security processes known as reverse DNS lookup (rDNS).
To prevent email from being 'returned to sender' you need to ensure that the IP address you use with your mail server is correctly associated with your domain name.
