How to add an MX record to your domain

Reviewed on 13 September 2023 • Published on 13 September 2023

Setting up an MX record ensures that your emails are delivered reliably. This page explains how to set up your own MX record, and how to set up Scaleway’s blackhole MX if you do not have your own MX server.

Security & Identity (IAM):

You may need certain IAM permissions to carry out some actions described on this page. This means:

  • you are the Owner of the Scaleway Organization in which the actions will be carried out, or
  • you are an IAM user of the Organization, with a policy granting you the necessary permission sets
Requirements:

How to add your own MX record

Important:

We recommend you use your own MX server if you have one. If you do not have an MX server, we recommend you use Scaleway’s blackhole MX, as it allows you to avoid email rejection. However, this also means that the emails sent back to the Scaleway blackhole MX, will be lost and unrecoverable.

  1. Add an MX record type in the root zone of your domain on your DNS zone.
  2. Enter a name of your choice in the Name field.
  3. Set 10 as a priority for your MX record.
    Note:

    Priority indicates the order in which your mail servers should be tried by a mail server that is attempting to deliver emails.

  4. Enter the name of your MX followed by a trailing dot in the Hostname field.
  5. Save your changes.

How to add Scaleway’s MX record

Important:
  • Scaleway provides its own MX server to improve email deliverability.
    However, Scaleway’s MX server is a blackhole. This means that any email sent back to it, will be lost with no possibility of recovery.
  • If you have no MX server, we recommend you use Scaleway’s blackhole MX to avoid getting your emails rejected.

  1. Add an MX record type in the root zone of your domain on your DNS zone.

  2. Enter a name of your choice in the Name field.

  3. Set 10 as a priority for your MX record.

    Note:

    Priority indicates the order in which your mail servers should be tried by a mail server that is attempting to deliver emails.

  4. Enter blackhole.scw-tem.cloud. in the Hostname field. Make sure you add the trailing dot at the end of the value.

  5. Save your changes.

    Important:

    Your changes might take up to 48 hours to apply.
