Setup DKIM (DomainKeys) with Postfix on Ubuntu - Debian
DKIM or DomainKeys Identified Mail is an authentication protocol used to validate the identity of a sender. It’s an important tool for preventing email spoofing, which is when a person impersonates another user and sends emails with their name and address. DKIM Key works by using an OpenDKIM or Domain Key to sign each message sent. The key is an encrypted string of characters unique to the sender and is used to verify the message comes from the sender’s domain. This makes it harder for malicious actors to send forged messages. DKIM Key also allows receivers to reject messages that fail authentication. This provides added protection against spoofing and other email-based attacks. It’s a crucial safety measure for any email server and one that can help protect your business and its customers.
