This document goes over what to do when you cannot add another MX record on your DNS domain server.
If you run into a DNS domain server platform that does not allow you to add additional MX records, you will want to use a CNAME record instead of the TXT SPF record. If you try to add both the SPF and CNAME record it will cause a conflict issue so you will want to do one or the other.
Steps
In the DNS domain server portal confirm that you cannot add an additional MX record.
If it shows that you are possibly replacing the MX record or does not allow for an additional record, that's when you'll enter the CNAME record instead of the MX records.
***Remove this TXT Record, if it exists***:
Type: TXTHost: idearoom-mail."yourdomainname.com"Value: v=spf1 include:mailgun.org ~all
***Add this CNAME record:
Type: CNAMEHost: idearoom-mailValue: idearoom-mail.idearoom.com
Make sure to also add the DKIM records as well. Get the values from SalesView.
Only add the DMARC record if one doesn't already exist.
Refresh DNS and Refresh Salesview
Click Verify email and should reflect green for verified.
Example: if your DNS domain server will not allow adding MX records, you will enter a total of three records. Image below shows the records that you would add to verify your email domain.
NOTE: Only add the DMARC record if one doesn't already exist.
Use SalesView to get the DKIM and DMARC record information and use this guide to get the CNAME record information.
