Any ideas how to fix my DMARC record that MX Tool says I am missing?
I have a Domain registered with GoDaddy and my DNS settings are here, but my mail is running of of a comcast MS Exchange server. Our email gets flagged as spam sometimes, and I'm wondering if this is why?

More Information About Dmarc Record
Hostname returned a missing or invalid DMARC record
DMARC Records are published via DNS as a text(TXT) record. They will let receiving servers know what they should do with non-aligned email received from your domain.
Domain-based Message Authentication, Reporting, and Conformance (DMARC) is a mechanism for improving mail handling by mail-receiving organizations. The ultimate purpose of DMARC, according toRFC-7489 is to provide a “mechanism by which email operators leverage existing authentication and policy advertisement technologies to enable both message-stream feedback and enforcement of policies against unauthenticated email. Email originating organizations utilize DMARC in order to express domain-level distribution policies/preferences for message validation, disposition, and reporting.
The DMARC Check will return either “Record Found” or “Missing/Invalid DMARC Record”. If the tests returns “Missing/Invalid DMARC Record” then we were not able to find a DMARC TXT record or there were syntax issues with your DMARC Record.
How DMARC Works:
DMARC policies are retrieved by the mail-receiving organization during a SMTP session, via DNS. When mail receivers query DNS, they look for a DMARC TXT record at the DNS domain that matches the one found in the RFC5322. From domain in the email message. If a policy is found, that policy is combined with the author’s domain and the SPF and DKIM results to deliver a DMARC policy result. This policy result will be either “pass” or “fail” and may cause a report to be generated. If a policy is not found, the DMARC module determines the organizational domain and repeats the attempt to retrieve a policy from the DNS.
Having a DMARC message handling policy is currently not required, but recommended as it improves mail-handling between both the sending and receiving organizations.

Hello @vfroment, you would have the option to create a DMARC record through your GoDaddy DNS management, however that would be considered custom DNS and our teams wouldn't be able to help you with the content or setup of a DMARC TXT record. You can find instructions for adding a TXT record to a GoDaddy domain here: https://www.godaddy.com/help/add-a-txt-record-1923
That being said, the issue that your describing probably isn't related to any DMARC settings. I'd recommend reviewing the bouncebacks and having your server administrator take a detailed look at the specific reason that the message was rejected by the destination server. Once they review the bounceback & the original message, you should have a better idea of what caused the rejection.

I have recently setup Symantec.Cloud Spam Filtering for my small business email. I am seeing the following error message for the following mail servers: 220.127.116.11, 18.104.22.168, 22.214.171.124, all GoDaddy IPs.
"The mail server at 126.96.36.199 is rejecting emails from the address email@example.com because of SPF enforcement."
Is there something I should do to my domain's dns entries or is this something at a higher GoDaddy level? Any assistance would be appreciated.
