The DKIM record is missing. This is easy to fix. Here is a bit of background information and what to do next.
What is DKIM
DKIM is one of the ways to authenticate email communication. Some information is added to your Web domain settings, and some other information is added to all the emails that we send for you. When the two match, the email is considered authenticated.
Why it matters
Adding DKIM authentication can increase your deliverability. That is: the percentage of your messages that are delivered to in the Inbox instead of the Spam folder.
Adding DKIM authentication
Adding DKIM authentication is easy. Here is what you need to do:
- Contact your Web hosting company, domain registrar, or network administrator that manages this domain
- Tell them that you need to make a change to the DNS (Domain Name System) records
- Ask them to create the following two CNAMEs...
ml01._domainkey.mydomain.com
- ... and:
ml02._domainkey.mydomain.com
- ... and point both of them to
dkim.musvc.com
- If a CNAME cannot be created, you can also establish DKIM authentication by adding the following TXT records to the DNS settings:
ml01._domainkey.mydomain.com IN TXT "k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCv+5lxtrNKrKKjF9Jvkidsk9UDOHht1tXZjhnt/ygrdFrQKKYxhgqSNtWBwA1TxukZIR382dYJhAHYDeeaGrUkf3C7VUzm+nO0fTMrN+lQXdYWIO9tTM9ZC3xVjG+uRrfnprJN8t2LfXwbC5oIGtRb8ZyQYiAhXO9qTHoAOK1/IQIDAQAB"
... and:
ml02._domainkey.mydomain.com IN TXT "k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCv+5lxtrNKrKKjF9Jvkidsk9UDOHht1tXZjhnt/ygrdFrQKKYxhgqSNtWBwA1TxukZIR382dYJhAHYDeeaGrUkf3C7VUzm+nO0fTMrN+lQXdYWIO9tTM9ZC3xVjG+uRrfnprJN8t2LfXwbC5oIGtRb8ZyQYiAhXO9qTHoAOK1/IQIDAQAB"
- Wait 24-48 hours: it takes a bit of time to changes to the DNS to propagate around the Internet
- Run this test again to confirm that the SPF record has been successfully updated.
What happens if you don't do it
If your emails are not authenticated by you, we will authenticate them for you. This will help with deliverability, but will result in some email clients showing "On behalf of..." or "Via..." next to your sender information. That's because email programs want to let the recipient know that another system was involved in the mailing.
