Greetings,

Thank you for asking.

Since you’re using Google Workspace, I’d suggest you to visit below article for more help:

From Mxtoolbox, helpful information about your inquiry:

I am afraid you cannot change the SMTP banner by default which they do advertise on the Internet since it’s in their hands, therefore you cannot change the PTR records for their mail server(s) as well.

Nevertheless, they’re just the warnings and I believe everything can function normally as expected if you’ve followed the guidelines how-to setup Google Workspace with 3rd-party DNS provider such as Cloudflare.

In case you experience some other issue, feel free to create another topic.
