The SPF (Sender Policy Framework) is an email validation system that tries to prevent the falsification of email addresses by verifying the IP addresses of the sending servers.
What it does is specify from which IP addresses emails can be sent from a certain domain.
The DKIM (DomainKeys Identified Mail) is an email authentication method that certifies that the mail comes from the sender indicated in the field desde. It uses public key cryptography to sign the emails, so if someone tries to manipulate the headers, it can be easily detected at the destination.
The operation is as follows: the issuing domain signs several email fields with its private key and adds the signature to the DKIM-Signature header. When the receiver receives the mail, it retrieves the sender’s public key in the DNS and uses it to verify that the signature is correct and the contents of the message have not been altered.
