DKIM and SPF (Email Authentication Methods)

MarkdownDKIM (DomainKeys Identified Mail) and SPF (Sender Policy Framework) are email authentication methods used to verify the authenticity and integrity of email messages. They help prevent email spoofing and improve email deliverability.
- DKIM adds a digital signature to outgoing email messages, allowing the recipient's mail server to verify that the message comes from an authorized sender and hasn't been tampered with. The sender's domain signs the outgoing email using a private key, and the recipient's mail server can verify the signature using the public key published in the sender's DNS records.
- SPF records are published in the DNS and specify the authorized mail servers (IP addresses or hostnames) for sending email on behalf of a domain. When an email is received, the recipient's mail server checks the SPF record of the sender's domain to verify if the sending server is authorized to send email for that domain.
