The big email providers, such as Google, Microsoft, Apple, and Yahoo, use something called SPF (Sender Policy Framework), DMARC (Domain-based Message Authentication, Reporting, and Conformance), and DKIM (Domain Keys Identified Mail) to prevent (among other things) people from sending emails from addresses (spoofing) that arent theirs.
