EXPLANATION:

Reverse DNS lookup for your mail server IP address is failing. IgLou requires that all connecting mail servers have established reverse DNS.

SOLUTION:

Reverse DNS is a way of associating an IP address with its domain name. 

Many large ISPs, including IgLou, now require that all mail servers sending mail to our customers must have established reverse DNS, regardless of whether the value matches the domain.

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.

If you were directed to this web page by an error message received from mailer-daemon, this means your ISP or corporate mail server is probably misconfigured.  Please notify the administrator of the mail service you are using of this error.
