Use the DKIM record checker to validate your DKIM records
DKIM (DomainKeys Identified Mail) is an email authentication technique that allows the receiver to check that an email was indeed sent and authorized by the owner of the sending domain. It works together with DMARC.
You need a valid DKIM record to implement DKIM. The Mimecast DKIM Record Check will use the domain name and selector to check for a valid published DKIM record. Because DKIM authenticates the reputation and identity of the sender, we recommend you carefully test any DKIM record updates before applying them.
