Email authentication

Email authentication is a set of techniques and protocols used to verify the legitimacy of an email sender's identity. It helps prevent email fraud, phishing attacks, and spam by verifying that an email message truly comes from the claimed sender and hasn't been altered during transit. Breaker adheres to SPF, DKIM, and DMARC email authentication protocols.
