Abstract
A method for optimizing and preventing failure of Sender Policy Framework (SPF) lookups by dynamically generating and returning flattened SPF records, recorded on computer-readable medium and capable of execution by a computer, the method comprising the steps of: requesting a regular SPF Record; receiving a SPF Record that includes an entry that points to a Proxy Server; the SPF Proxy server looking up a canonical SPF record optionally containing many included domains; and the SPF Proxy server flattening the canonical record into IP addresses and optionally sub records depending on the length of the flattened response.
