What are DKIM and SPF Records?

DKIM stands for DomainKeys Identified Mail which helps to prevent email spam and improves email delivery in different ways. It checks and verifies whether the messages sent are associated with the correct domain or not.

DKIM is a DomainKeys Identified Mail (DKIM) signature protocol. It is an open standard that allows a domain to digitally sign messages. DKIM is designed to provide high-level security and authentication for email messages, and it is widely used by enterprises and organizations around the world. In order to receive email from a domain, the receiver must first verify that the domain is not malicious.

To do this, the receiver performs a DKIM signature check. If the signature check passes, the receiver can then proceed to the email itself. DKIM provides two primary benefits:

1. It provides high-level security for email messages by preventing unauthorized parties from tampering with the message and changing its content.

2. It provides authentication for email messages by verifying that the message was sent by an authorized party.

SPF is composed of four principles:

1. Maintain a diverse set of addresses (e.g., your company name, a personal email address, and a business email address).

2. Use unique email addresses for each organization (e.g., company [email protected], personal [email protected], and business [email protected]).

3. Use different email servers for each organization (e.g., company [email protected], personal [email protected], and business [email protected]).

4. Use different domains for each organization (e.g., company [email protected], personal [email protected], and business [email protected]).

5. Use different email delivery methods for each organization (e.g., company [email protected], personal [email protected], and business [email protected]).

6. Maintain a high degree of subjectivity in selecting the messages to send (e.g., use only those messages that are relevant to your organization).

7. Be diligent about evaluating the effectiveness of your email sending efforts.
