Check that your DKIM record is correctly implemented and establishes you as the authorized owner of your email sending domain.
Enter a DKIM selector and a domain to look up the associated DKIM record.
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.
