Adding MX records to Name.com

These instructions are for users who purchased their domain on Name.com and would like to change their MX (mail exchange) records so they can send and receive mail with Fastmail.

Changing your MX records is the best option for users who have a website on their domain hosted with another service. For users who do not have a website hosted at their domain, switching nameservers to Fastmail is usually a better option.

This guide covers three steps to setting up your domain:

Step 1: Add your domain to Fastmail

We have a domain setup wizard to help you get your domain working as quickly and easily as possible.

After you have purchased your domain from Name.com, you can get to our setup wizard using these steps:

  1. Log in to your Fastmail account and go to the Settings → Domains screen.
  2. Click Add or buy domain, then select Use a domain you already own.
  3. Enter your domain into the text box and click Continue.

Follow the steps in the setup wizard to add your domain and email addresses to Fastmail. To have the wizard provide you with steps to update your MX records by default, choose Yes when you are asked if you have a website.

For more information, please see our Using the domain setup wizard help page.

Please note: If you are on a legacy plan, the domain setup wizard can only set up email addresses, not users. You will need to add users manually in order to create additional user accounts at your custom domain.

Step 2: Edit your MX records in Name.com

Note: We recommend making these changes at a time that you do not expect much mail to be sent to your domain.

  1. Log in to your account at Name.com and go to My Domains.
  2. Find the domain you want to use with Fastmail, and click on it to find the settings.
  3. Click Manage DNS Records in the DNS column.
  4. You should see a section where you can add new DNS records, with a drop down for Type. Click the drop down, and choose MX. Create your first record with the following details:
Host Value Priority
@ in1-smtp.messagingengine.com 10

5. Now add a second MX record with the following details:

Host Value Priority
@ in2-smtp.messagingengine.com 20

6. Click Add Record. 

When you are finished with the above steps, your MX records should look like this:

MX records added at Name.com

Please make sure that these two MX records are the only MX records present on the domain. Any other MX records should be removed.

Step 3: Set up DKIM and SPF

Your domain should now be ready to receive messages. In order to make sure your sent messages reach your recipients, there are a couple more records to add in your Name.com account.

Set up DKIM

  1. Add three new DNS records in the same place you added your MX records. 
  2. In the dropdown for the record type, choose CNAME.
  3. Enter the details as follows (make sure to replace {mydomain.com} with your actual domain name):
Type Host Answer
CNAME fm1._domainkey fm1.{mydomain.com}.dkim.fmhosted.com
CNAME fm2._domainkey fm2.{mydomain.com}.dkim.fmhosted.com
CNAME fm3._domainkey fm3.{mydomain.com}.dkim.fmhosted.com

Set up SPF

  1. Add another DNS record in the same place you added your CNAME records. 
  2. In the dropdown for the record type, choose TXT.
  3. Enter the details as follows:
Type Host Answer
TXT (leave blank) v=spf1 include:spf.messagingengine.com ?all

When you are finished, your domain control panel should look like this (with your domain name in the blank spaces):

Domain setup complete

Check your domain

Once you have finished this step, your domain should be working with Fastmail.

To check that all your settings are correct, log in to your Fastmail account and go to the Settings → Domains screen. Click Recheck DNS. Your domain should now say Active. MX records set.
