Configure a company domain for email masking

Setting up a company network to support email masking.

Complete the steps in Prepare for email masking to acquire the DNS CNAME records to add to the company's public DNS. These records identify the Medallia email-masking SPF hosts for the configuration.
The company's IT or infrastructure group configures the company's public DNS records to point SPF requests to the Medallia SPF hosts. For information about the concepts, see Email delivery components.
  1. Add the provided CNAME records the company's public DNS.

    Medallia provides two host name records to allow one configuration to remain running while service is performed on the other. Both need to be added to the DNS. The records look similar to this (wrapped lines) example:

    medallia1._domainkey.feedback.example.com 3600 IN CNAME medallia1.feedback.example.com.dkim.medallia.com
    medallia2._domainkey.feedback.example.com 3600 IN CNAME medallia2.feedback.example.com.dkim.medallia.com
    
    The records tell receiving email hosts to use the Medallia hosts to resolve DKIM questions.

    Parts of the DNS record for 'host.example.com 3600 IN CNAME dkim.medallia.com'. When looking up the the host at the beginning of the record, and instead, lookup the host at the end of the record. Cache the result for 3600 seconds.

  2. Verify the DNS configurations.

    Verify DNS configurations using command-line tools or web utilities. This discussion uses the dig UNIX command-line utility on macOS and nslookup on Windows. You can also use web-based tools such as Dig web interface.

    Note: Some implementations of dig and nslookup might not support all options shown below. If needed, check the documentation for your specific tool.

    When making the query, include the subdomain and an option identifying what you are looking for. For example, to verify the record for the medallia1 example host:

    $ dig TXT medallia1._domainkey.feedback.example.com
    nslookup -type=txt medallia1._domainkey.feedback.example.com
    
    The result should look similar to this, where there are 3 records the "ANSWER SECTION", and the first record matches the DNS record provided in Step 1, above.
    ;; ANSWER SECTION
    medallia1._domainkey.feedback.example.com 3600 IN CNAME medallia1.feedback.example.com.dkim.medallia.com
    medallia1.feedback.example.com.dkim.medallia.com 3600 IN CNAME medallia1.domainkey.medallia.com
    medallia1.domainkey.medallia.com 21585 IN TXT "v=DKIM1; k=rsa; p="…" "…"
    

    Complete this test for both CNAME records, such as medallia1 and medallia2 in the example DNS record.

  3. Notify Medallia Support that the DNS configuration is complete.
    In the same Support ticket created in Prepare for email masking, add a reply and tell Support the DNS configuration is complete.
    Support will verify the configuration and when approved, will provide email addresses to use later when validating the configuration.
After receiving Support approval, the company domain is now ready to support email masking.
To complete the setup for email masking, proceed to Configure and validate email masking.
