Frequently Asked Questions
DKIM (DomainKeys Identified Mail) is an email authentication method that uses cryptographic signatures to verify that an email was sent by an authorized server for the domain.
The selector is a string used to identify the key record. Common selectors are 'default', 'google', 'selector1'. You need both domain and selector to look up the DKIM record.
The DKIM public key is stored in a TXT record at {selector}._domainkey.{domain}. For example, default._domainkey.example.com.
