Validates that the DKIM record is formatted correctly and has no errors.
A DKIM record is a DNS TXT record that contains a public key that can be used by an email recipient to cryptographically verify that the email came from the website that it claims to come from. This test will check the record, make sure there aren't any syntax errors and report on what it finds. Here is an example of what a DKIM record might look like:
v=DKIM1; k=rsa; p=MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMI....
For more information on the DKIM record format, please read more at Wikipedia.
