SPF Record

Sender Policy Framework (SPF) Records are used for email validation to mitigate spam. SPF records allow domain administrators to define all hosts allowed to send mail for a domain by creating a specific TXT record that is then used by mail exchangers to validate a senders identity. The data of an SPF record must be enclosed in quotations.

The original specifications for SPF required storage of SPF information for domains within TXT type records. Later specifications created the SPF type record. Currently, there are no SPF implementation that will not use TXT type records if they are present, so SPF type records are not required. There are, however, many SPF implementations that will not use SPF type records, so TXT records remain required. It is a good idea to have identical SPF information within a domain under both a TXT type record and an SPF type record.

SPF records can be generated using a free online tool from Microsoft located here.
