DomainKeys Identified Mail (DKIM) integration
The DomainKeys Identified Mail (DKIM) functionality provides an email authentication method to help ensure that a message is not modified while it is in transit from an organization’s protected domains. The implementation depends on a set of keys (private and public), which a recipient domain can use to verify the sender domain. DKIM settings are configured on the page .
A DKIM integration has the following components:
- Email signing
- Email verification
For the signing element, a private key resides in the mail transfer agent, providing a digital signature that is added to the header of each message sent from a protected domain. A public key is generated and published in the DNS as a text record that is used by a recipient mail system in the verification process.
A signing rule associates specified sender domains with a private and public key set.
