Overview:

DKIM, or DomainKeys Identified Mail, is an email authentication method designed to enhance the security of email communication. It works by allowing a sender to digitally sign their emails, providing a mechanism for the recipient to verify that the email was indeed sent by the claimed sender and that it hasn't been tampered with during transit.

Our Hosted Exchange service uses a simple CNAME record to validate your email by DKIM, adding the record below to your DNS Zone will ensure that you have been validated.

Method:

1. Log into your DNS provider's DNS editor. If you need assistance with this, you may need to reach out to your DNS provider for more information.

2. Add a new CNAME Record to your DNS Editor.

3. Enter the following Name and Value to the new record:
   (Be sure to replace the ‘YOUR.DOMAIN” section with your real domain name)

   1. Name: m21hostedexchange._domainkey.YOUR.DOMAIN

   2. Value: m21hostedexchange._domainkey.micron21.com

   3. TTL: 3600 (Or match any existing TTL on other TXT Records already associated with your domain name)

      
      

4. Save the new record and allow up to 48 hours for DNS propagation.
