DNS Settings - MX & SPF records

DNS MX Records

Configuring your DNS records is a critical step in putting your DirectMX service to use for you! You will need to configure your DNS to use the following servers as your inbound MX hosts:


An example of a BIND configuration for this are the following lines:
@     IN    MX    10 mx1.directmx.com.
@     IN    MX    20 mx2.directmx.com.

DNS SPF Records

We strongly recommend that you add SPF protection to your email service. This prevents people from falsely sending email as you, but is also a required step if you are using DirectMX for outbound email, or smart-hosting.

An example of a valid BIND configuration is the following:
@    IN    TXT   "v=spf1 a mx ptr include:directmx.com ~all"

SPF can be complex to setup, and we highly recommend contacting us to confirm that it looks right and is working - please give us a call!
