Cloudflare DNS Settings to Forward Email with ForwardMX

Using ForwardMX with Cloudflare is one of the original use cases that we built the service for.

In this knowledgebase article, we will go through the whole setup to use ForwardMX as your MX server and receive all your domains emails while using Cloudflare as DNS provider. Now let’s get started.

We assume you already have setup your domain with Cloudflare.

If that is not the case, check out this guide by Cloudflare.

1. Go to your DNS settings

Open Cloudflare and switch to the domain you want add ForwardMX to. You will have several options on the top; choose the “DNS” one.

2. Add MX Records

On the DNS panel, click the "Edit" and choose "Delete" for any existing MX records.

You'll need the MX Records for your ForwardMX service, which you can find under "MX Records and Setup Instructions" in your ForwardMX account.

For the purposes of this example, we'll use "mx1.forwardmx.io" and "mx2.forwardmx.io", although the ones in your account may be different from this.

Then click "Add Record", select MX from the first dropdown, set the name to "@" and the Mail server to "mx1.forwardmx.io" with Priority 10, then click "Save".

@ means your domain's top level in Cloudflare's DNS configuration.
If you add any other value here, the email would be only working on a subdomain.
For example, if you enter www instead of @, it will be only be for emails sent to [email protected] which is probably not what you want.

Repeat that step for the second mail server record.

3. Configure the TXT record

Click on Add Record, choose type "TXT", name @ (unless you're configuring email on a subdomain) and the value:

"v=spf1 include:_spf.forwardmx.io -all"

And then click "Save"

4. Done

If everything is right it should look something like this:

Now wait for DNS propagation for these changes, which can be as quick as 5 minutes and as long as 48 hours, and you are ready to receive emails on your Cloudflare domain through ForwardMX.
