Client host rejected [ip address]: rDNS indicates dynamic address

Most internet customers will receive an IP address automatically (dynamically) from their ISP (Internet Service Provider). Some ISP's assign reverse DNS records to their dynamic IP pools. Spammers, viruses, and malware will exploit this loop-hole to trick other mail servers into thinking that they are a legitimate mail server. We have implemented this check into order to circumvent this spamming technique. If you receive this error please contact your email provider for help in resolving the error. If you are an Eagle customer the most likely cause is an error in your mail client's configuration. Please contact our support department if our help pages fail to resolve the problem.

For example:

Reverse record [ =>]

In order for your emails to be delivered, we need a little information from you, the sender.
