What is email spoofing and how do I stop it?
Short answer: Email spoofing is when someone sends email that fakes your address in the From line; you stop it by publishing SPF, DKIM and a strict DMARC policy.
The full answer
Email was designed without built-in identity checks, so anyone can type any From address. Scammers use this to send fake invoices and password requests that look like they come from you.
With DMARC at p=reject, major mail providers refuse those forged messages before they reach anyone.
