What are Txt and SPF Records?

Sender Policy Framework or “SPF” fights return-path address forgery and makes it easier to identify spoofs. SPF records are DNS TXT resource records that provide a list of servers that may legitimately send mail on behalf of a domain. This allows domain owners to identify sending mail servers in DNS. SMTP receivers verify the envelope sender address against this information, and can distinguish authentic messages from forgeries before any message data is transmitted. By correctly setting up your SPF records, you are contributing to the worldwide fight against the current spam epidemic.
