1Add a DMARC record: _dmarc.yourdomain TXT "v=DMARC1; p=reject; adkim=s; aspf=s; rua=mailto:dmarc@yourdomain"
Without DMARC, receiving mail servers have no way to know what to do when SPF or DKIM checks fail. Anyone can send emails pretending to be from your domain, and most servers will deliver them. DMARC with p=reject tells receivers to block unauthorized emails entirely.
2Harden your SPF by replacing ~all with -all (hardfail)
With ~all (softfail), unauthorized senders are flagged but emails are usually still delivered. Switching to -all (hardfail) explicitly tells receiving servers to reject emails from unauthorized sources, providing much stronger protection against spoofing.
3Add MTA-STS to enforce TLS encryption for incoming emails
Without MTA-STS, an attacker performing a man-in-the-middle attack can downgrade the connection between mail servers to plaintext, intercepting emails in transit. MTA-STS tells sending servers to only deliver via TLS with a valid certificate, preventing downgrade attacks.
