Hey Mikhail! 👋

To set up CNAME records for Proton Mail DKIM protection in DigitalOcean, you should be able to configure these records without issues. Proton Mail typically provides the CNAME records, and you can add them in your DigitalOcean DNS settings by going to the Networking section, selecting your domain, and adding a new CNAME record.

Could you share more details about the issue you’re encountering? For example:

Are you seeing an error message when trying to add the CNAME record?
Is the issue related to the format or value of the record provided by Proton Mail?
