How to.....failing messages from other service providers to send summaries to the cloud service

[JeffreyYeroian4360]

I am trying to implement this. I was told I need an email address for the DNS change to send other service providers failed email messages to the cisco cloud for processing.

Summary

In connection with Your use of DMP, You can, at your discretion, publish a DMARC policy via your own DNS infrastructure. This policy instructs email service providers (“ESPs”) to send numerical summaries to the Cloud Service about messages which have been processed and which appear to come from Your domains. You may also request that these ESPs send examples of messages failing email authentication to the Cloud Service.

One of the best ways to learn is executing commands from the ESA cli.
You can see what other companies publish for their own records.
