What are SPF and DKIM and do I need to set them up?

Do I need to set the SPF and DKIM records? How do I do that in EasyMail7?

Authentication helps legitimate senders prove that their email isn’t forged and can help receiving servers like ISPs and corporate email servers control inbound spam. There are a variety of authentication methods: SPF, SenderID, DomainKeys, and DKIM.

SPF allows the owner of an Internet domain to specify which computers are authorized to send mail with sender addresses in that domain, using Domain Name System (DNS) records. Receivers verifying the SPF information in TXT records may reject messages from unauthorized sources before receiving the body of the message. SPF and SenderID allow a domain owner to add a file or record on the server that the recipient server cross-checks.

DKIM and DomainKeys embed information within the email, making it harder to forge. The DKIM record allows to digitally “sign” your emails for your domain.

When you add authentication information to your domain, an added benefit is that many ISPs use authentication to track sending reputation. With authentication handled by your domain, reputation with the receiving ISPs is influenced by your domain and the emails sent on behalf of your domain. This means you maintain control over the emails that affect deliverability for your domain. A positive reputation for your domain builds trust and improves deliverability, affecting whether your emails are caught by spam filters and how quickly the receiving servers will accept mail from your domain.
