It is an anti-forgery tool.
SPF as defined in RFC 4408, is an email validation system designed to prevent e-mail spam by addressing a common vulnerability, source address spoofing.
Quoted from the RFC:
"
The current E-Mail infrastructure has the property that any host injecting mail into the mail system can identify itself as any domain name it wants. Hosts can do this at a variety of levels: in particular, the session, the envelope, and the mail headers. Although this feature is desirable in some circumstances, it is a major obstacle to reducing Unsolicited Bulk E-Mail (UBE, aka spam)."
I think this argument is now over.
