Change Your MX Records

To route incoming email for your domain through the Mail Assure filtering cloud you need to update the MX records in your domain provider's DNS settings.

Prior to changing the MX records, you should check your records' TTL value. We recommend a maximum value of '3600' in order to propagate any DNS changes faster. Higher TTLs can lead to spam not being filtered by our nodes, until the previous record expires, when the TTL is reached.

  1. In your domain provider's DNS control panel add the following records:
  2. Global MX Records (Recommended)

    • mx1.mtaroutes.com (priority 10)

    • mx2.mtaroutes.com (priority 20)

    • mx3.mtaroutes.com (priority 30)

    • mx4.mtaroutes.com (priority 40)

    We recommend configuring your domain to use the above global MX records. However, where there is a requirement to route data through a specific geographic territory, the below region-specific MX records may be used:

    EU Region

    • mx1-eu.mtaroutes.com (priority 10)

    • mx2-eu.mtaroutes.com (priority 20)

    • mx3-eu.mtaroutes.com (priority 30)

    • mx4-eu.mtaroutes.com (priority 40)

    Americas Region

    • mx1-us.mtaroutes.com (priority 10)

    • mx2-us.mtaroutes.com (priority 20)

    • mx3-us.mtaroutes.com (priority 30)

    • mx4-us.mtaroutes.com (priority 40)

    UK Region

    • mx1-uk.mtaroutes.com (priority 10)

    • mx2-uk.mtaroutes.com (priority 20)

    • mx3-uk.mtaroutes.com (priority 30)

    • mx4-uk.mtaroutes.com (priority 40)

  3. Remove the original MX records.
Some DNS control panels require you to use a trailing dot (.) after the hostname. Please check with your DNS provider if this is the case for you.

Removal of old MX records is required to make sure all emails are filtered through the Mail Assure cloud, as spammers actively try different MX records (such as the highest numbered priority) to bypass spam filters.

DNS changes may take some time before they are picked up by the DNS resolvers world-wide, so email may continue to deliver directly to the original MX records without filtering for some time depending on the TTL value set on the DNS server.

You can check using the Log Search if the message has passed through the Mail Assure filtering nodes.

To check that your system is using the correct MX records, use the MX Verification Tool.

To Access the Log Search:

  1. In the Admin Level Control Panel, select Domains > Overview.
  2. Click on the relevant domain to display the domain's Dashboard.
  3. In the Incoming panel, click on Log search. For instruction on how to use this page, see View Incoming Log Search.
