The SPF record is missing. This is easy to fix. Here is a bit of background information and what to do next.
...
SPF (Sender Policy Framework) is one of the ways to authenticate email communication. Some information is added to your Web domain settings indicating that certain systems are authorized to send email on your behalf. Adding SPF authentication can increase your deliverability. That is: the percentage of your messages that are delivered to in the Inbox instead of the Spam folder.
What happens if it's missing
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 ("us") was involved in the mailing.

Adding SPF 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
- If you are not already publishing a SPF record, ask them to add the following TXT record:
v=spf1 include:musvc.com ~all
- If you already have a SPF record in place (e.g.: you have a TXT record starting with v=spf1) then you should only add the "include:musvc.com" before the final "all" keyword
Example: v=spf1 include:mydomain1.com include:mydomain2.com include:musvc.com ~all
...
- 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.
