Sender Policy Framework (SPF) records allow domain owners to specify which hosts are permitted to send email on behalf of their domains. Normal SMTP allows any computer to send an email claiming to be from anyone. Thus, it's easy for spammers to send emails with forged From: addresses. SPF allows a domain owner to use a special format of DNS TXT records to specify which machines or hosts are authorized to transmit email for their domain; this makes it difficult to forge From: addresses.
