If the DKIM record fails: Check the Host field value: Depending on your DNS zone, the Host field may only accept either litesrv._domainkey (without your domain) or litesrv._domainkey.yourdomain.com, so try both. Check the record type: The DKIM record should be CNAME type. Common delay: Sometimes it can take up to 48 hours to completely update. Most of the time, however, it is approved and updated in minutes
