Authenticating email with SPF

The Sender Policy Framework (SPF) is an email validation standard designed to combat email spoofing. Spoofing is the act of making an email sent by a malicious actor look like one sent by a legitimate user. For information about configuring SPF for your Amazon WorkMail-enabled domain, see Authenticating email with SPF in Amazon SES.
