Certain browser environments restrict the use of 1st-party cookies (e.g. Safari's ITP) and limit our ability to persist user consent records for a longer period of time. In order to side-step these restrictions, you have the option to set cookies through the server rather than having to rely on
document.cookie. To accomplish this, you need to set up a CNAME DNS record for a 1st party subdomain and include it in the website's configuration snippet.
Note: If you already have a CNAME record pointing to either the mms.sp-prod.net or message.sp-prod.net, Sourcepoint recommends setting up a new subdomain to simplify the transition to the new single name CNAME solution.
There are two ways to set up the CNAME record for your website implementation:
The difference between the two methods depends on whether Sourcepoint is setting up the TLS certificates for https traffic or whether you are setting up your own TLS certificates and providing Sourcepoint with the details.
Note: In order to reduce the risk of being identified by block lists, Sourcepoint recommends that your organization avoids using cmp or privacy in your subdomains (e.g.
Instead, consider using the following or a variation of the following:
Sourcepoint configures the TLS certificate
- Set up a 1st party subdomain and create a CNAME record pointing to
- Notify Sourcepoint that the CNAME record has been set up.
- Sourcepoint establishes a TLS certificate for the cname record.
- Sourcepoint then creates an account specific CDN endpoint. If the account ID is 222 then Sourcepoint sets up the subdomain of
- Sourcepoint then notifies you that the CDN endpoint has been set up.
- Finally, update the CNAME record to point to the new Sourcepoint CDN endpoint. In our example, this is
The Site Sets Up The TLS Certificate
- Set up a 1st party subdomain and inform Sourcepoint that you want to use your own TLS certificate.
- Sourcepoint provides you with the CSR file for the subdomain TLS cert application.
- Apply the certificates and send the certificate back to Sourcepoint.
- Sourcepoint tests and verifies the certificate.
- Sourcepoint deploys the certificate.
- Sourcepoint then creates an account specific CDN endpoint. If the account ID is 222 then Sourcepoint sets up the CDN endpoint of
- The site then updates the CNAME record to point to the new Sourcepoint CDN endpoint. In our example, this is
The subdomain for which the CNAME record was created is referenced in the parameters for the website configuration snippets.
