What is an SPF record?

An SPF record is a type of DNS record that identifies which mail servers are permitted to send email on behalf of your domain. 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 suggested that both SPF and TXT records be used, although either by itself was acceptable. So it is a good idea to have identical SPF information for a domain under both a TXT type record and an SPF type record.
