DKIM signature for outgoing messages

A DKIM signature for outgoing messages is a digital signature added to messages sent from email addresses of a certain domain for purposes of identifying users by the name of the corporate domain.

The DomainKeys Identified Mail (DKIM) technology lets the recipient of a message verify that the message was actually sent from the declared domain. The DKIM technology is designed to combat forged sender addresses, which are often used in phishing messages and spam. Instead of a traditional IP address, the sender is identified using a digital signature associated with the domain name of the organization. The signature is automatically checked at the receiving side. Sender authentication is achieved using the Domain Name System (DNS), which allows sending public encryption keys.
