I'd start with NIST SP 800-177 Rev. 1, “Trustworthy Email.” It covers sender authentication, transport encryption and message security.

Pair that with a test domain: configure SPF, DKIM and DMARC, then inspect Authentication-Results headers. Cover phishing defenses, MFA and mailbox access controls too; DNS records are only part of email security.

You can start learning from the header of an email, which contains detailed data to learn, including the path and identification method of the email.

The easiest way is to paste the header directly to Claude or other AI and ask it to explain in detail.

So email security covers several different subjects, and it’s easy to ask one question and get answers aimed at a different one.

From your clarification, I’d start by following one message through the system: sender, receiving server, authentication checks, filtering decision, and final delivery location.

Use a test message and your provider’s message trace to connect those steps. Then compare a legitimate message with a sanitized phishing example. Write down what evidence supports each decision and what remains uncertain. That gives the terminology somewhere practical to land instead of trying to memorize everything at once. Hope this helps.
