If you're using MXroute for email delivery, it's important to configure your SPF, MX and DKIM records correctly to ensure smooth email authentication and prevent delivery issues. This guide will walk you through updating your DNS settings for MXroute.

What Are SPF, MX, and DKIM Records?

• SPF Record: Helps prevent email spoofing by specifying which mail servers are authorised to send emails on your domain’s behalf.
• MX Record: Directs incoming emails to the correct mail server for your domain, ensuring proper email delivery.
• DKIM Record: Adds a cryptographic signature to your outgoing emails, verifying their authenticity and preventing tampering.
• TXT Record: A flexible DNS record used for various purposes, including email validation, verification, and security policies.

Adding Your MXroute SPF Record

• Locate your existing SPF record in your DNS settings. It will start with something like: v=spf1

• Replace your existing SPF record with the following:

  include:"v=spf1 a mx include:mxroute.com ~all"

Example before update

  "v=spf1 +a +mx +ip4:192.168.1.1 include:example.com ~all"

Example after update

  "v=spf1 a mx include:mxroute.com ~all"

• Save the updated SPF record.

Adding the MX Records for MXroute

You’ll need to add the following MX records to ensure proper email routing:

• Record Name: domain.com
• Record Value: server.mxrouting.net.

• Priority: 10

• Record Name: domain.com
• Record Value: server-relay.mxrouting.net.
• Priority: 20

Note: Replace domain.com with your actual domain name and server with the MXroute server assigned to you.

Configuring DKIM for MXroute

DKIM (DomainKeys Identified Mail) ensures that your outgoing emails are signed and verified for authenticity.

• Log in to your MXroute DNS Control Panel.
• Locate the DKIM record for your domain. Each DKIM key is unique to your account.
• Copy the provided DKIM TXT record from MXroute. It will look something like this:
  • Record Name: x._domainkey.domain.com
  • Record Type: TXT
  • Record Value: (Your unique DKIM key from MXroute)
• Add this DKIM record to your DNS settings.
• Save the changes and allow time for DNS propagation.

Conclusion

Properly updating your DNS records ensures that your emails are authenticated correctly, reducing the chances of being marked as spam or rejected.

Once you've made these changes, be sure to verify that your DNS records have propagated using an online DNS lookup tool. Propagation may take anywhere from a few minutes to 48 hours.
