Step 3: Change the DNS MX records

After completing Step 1: Adding users and Step 2: Confirming your Inbound Mail address, you can make the following DNS MX record changes to get your Mailprotector email security service up and running:

Important:  Prior to making these DNS changes, please ensure that you have allowed Mailprotector's IP addresses through your firewall.  You can find the complete list of IP addresses here.  We also recommend you confirm that we can connect to your mail server from our datacenters, after making that change.

DNS MX Record Changes

  • Delete all current MX records
  • Enter new MX Records based on your geographic region:
    United States
    Asia Pacific

    domain.tld = The domain you are setting up.
    Example: For Domain Name
    10 MX


Question: "Can I keep my old MX record in there as a backup or higher priority record than Mailprotector's MX record"?

Answer: While technically there are no issues with this configuration, you will be leaving direct access to your mail server open. It is common for spammers to deliver to backup/alternate MX records to bypass security and other filters. We also advise that after your MX records have fully propagated, you restrict SMTP (port 25) traffic to only accept from Mailprotector ranges. This will guarantee all email is scanned by Mailprotector systems.
