CloudFlare CName DKIM Configuration

Before you begin this process make sure you add SPF, DKIM, DMARC, and ADSP Records

To properly protect your outbound mail, add your SPF, DKIM, DMARC, and ADSP records while you're in there changing your MX record. 

We have a primer on what all these are for, if you're interested here: https://support.mailroute.net/hc/en-us/articles/360061128614-Email-Authentication-An-Explanation-and-Exploration

We have a Knowledge Base articles for each of these:

• https://support.mailroute.net/hc/en-us/articles/360021568194-Setting-Your-SPF
• https://support.mailroute.net/hc/en-us/articles/115009100687-Implementing-DKIM
• https://support.mailroute.net/hc/en-us/articles/360062946093-Implementing-DMARC-for-the-MailRoute-Outbound-SmartHost-Service

After you have done the outbound authentication configurations you can begin to configure your server for outbound relay.
