From your mail server log, if you can see "Unauthenticated email from zuora.com is not accepted due to domain's 5.7.1 DMARC policy", it means it is rejected due to DMARC policy.
Here is the sample log recorded on Zuora end.

From dmarc org site https://dmarc.org/overview/ The bounced issue happens due to the receiver's dmarc policy. After the email is sent from zuora end, the dmarc is controlled by the receiver.
