The returnpath CNAME is for the processing of non-delivery reports (¨bounces¨)

The Return-Path CNAME points the return path of Zivver emails back to Zivver. These are the consequences:

• Zivver receives non-delivery reports (NDR) and the other email feedback that the receiving mail servers sent.
• Zivver can pass this feedback to the Zivver user. For example, Zivver tells the user whether a Zivver message caused an NDR.
• The email passes the SPF alignment test. This is a part of DMARC.

When you create a CNAME record, you create a subdomain zivverbounce. and point it to returnpath.zivver.com. With this, email providers can route emails back to Zivver.

The administrator must create a subdomain zivverbounce.yourdomain.com and set the CNAME record to point to that subdomain. Zivver does checks only on the zivverbounce subdomain for the existence of a CNAME record. Zivver ignores every other subdomains that you create and to which you added CNAME records.

If a CNAME record is configured, do not set other records for the same subdomain.
