DKIM (DomainKeys Identified Mail) is an email authentication method, designed to detect forged addresses in emails (spoofing). It allows the user to make sure that the email they received doesn’t come from a specific domain and has really been authorized by the said domain owner. The goal is to deter forged sender addresses in the email, a technique often used in phishing and spam email.

Usually, DKIM signatures are not visible to the final users, and they are placed or verified by the infrastructure, not by the senders and the receivers of the email.
