Documentation from Cloudflare answers that implementing DKIM (DomainKeys Identified Mail) adds a digital signature to outgoing emails, which can be verified by receiving servers. This helps to ensure that the message has not been altered during transit and that it truly originated from the claimed sender. Using DKIM can improve email deliverability and reduce the likelihood of spammers using your address.

Documentation from Microsoft Support explains that implementing SPF (Sender Policy Framework) records can help prevent spammers from using your domain to send unauthorized emails. SPF allows you to specify which mail servers are authorized to send email on behalf of your domain, and receiving servers can then verify that incoming messages are coming from an approved source.

Documentation from Google Workspace Admin Help shares that DMARC (Domain-based Message Authentication, Reporting & Conformance) builds upon SPF and DKIM to provide a policy for how receiving mail servers should handle emails that fail authentication checks. By implementing a DMARC policy, you can instruct receiving servers to reject, quarantine, or accept messages that appear to be spoofed, thus preventing spammers from using your email address in replies.

Documentation from RFC explains that using ARC (Authenticated Received Chain) can help with email forwarding issues. It allows intermediate mail servers to pass along authentication results, helping the final recipient to verify the email's legitimacy, even after it has been forwarded multiple times.
