At Millionaire.email, we take email security to the highest level. Email spoofing, phishing, and man-in-the-middle (MITM) attacks are on the rise—but we’re staying far ahead of the curve. Every account is backed by fully configured SPF, DKIM, DMARC, MTA-STS, and DNS CAA records to authenticate your messages and shield your identity.

What Is Email Authentication and Why Does It Matter?

Email authentication ensures your emails are genuinely sent by you—not someone pretending to be you. These protocols are essential for maintaining trust, improving deliverability, and stopping cyberattacks in their tracks.

1. ✅ SPF (Sender Policy Framework)

SPF authorizes specific IP addresses to send email on behalf of millionaire.email. Unauthorized senders? Instantly rejected.

🔗 Check SPF Record

2. ✅ DKIM (DomainKeys Identified Mail)

DKIM digitally signs outgoing messages so recipients know the content hasn’t been altered. It verifies message integrity and domain ownership.

3. ✅ DMARC (Domain-based Message Authentication, Reporting & Conformance)

DMARC aligns SPF and DKIM to instruct receiving servers on how to handle suspicious emails—reject, quarantine, or report them. We set strict DMARC enforcement to prevent spoofing.

🔗 Check DMARC Record

4. ✅ MTA-STS (Mail Transfer Agent Strict Transport Security)

MTA-STS forces encryption during mail transmission. It ensures your emails are not intercepted or altered in transit.

🔗 Check MTA-STS Record

5. ✅ DNS CAA (Certification Authority Authorization)

DNS CAA limits which Certificate Authorities (CAs) can issue SSL/TLS certificates for our domain, protecting against rogue certs and MITM attacks.

Why It Matters for You

When you send an email from yourname@millionaire.email, your recipient sees a verified, trusted message—not a phishing attempt. Your messages are less likely to land in spam folders, and your domain reputation stays clean.

You don’t have to configure any of this manually—we handle it for you. From day one, every Millionaire.email account comes with Bank/Gov/enterprise-grade email authentication built in.

Final Thoughts

Most email services skip these critical protections or leave users to figure them out. At Millionaire.email, your security is our default. Whether you're an individual, investor, or public figure, your communications deserve elite protection.
