Why email authentication is good for your business

Sender Policy Framework

SPF is a method which servers receiving email can use to verify that the person sending the message is indeed allowed to send emails from that domain name. It’s a small piece of text that is stored in the DNS record of your domain name which validates the originating email address of your message. When a system receives email from you, it checks this record against the details of the server that sent your message.

DomainKeys Identified Mail

DKIM is like an encrypted digital signature which can be used to verify the credentials of email traffic. It works by using a private domain key to encrypt your domain’s outgoing mail headers, and adding a public version of the key to the domain’s DNS records. Comparison of the original and received headers is used to check that your email comes from your domain and that it hasn’t been changed along the way.
