How to white list dmarc domain?

[Sergio]

Hello, Sarah.

On my server I have blocked some file extensions and .gz was one of them.

Unfortunately a few companies that send DMARC reports uses .gz files and are blocked by MailScanner.

Is there a way to create a kind of filetype.whitelist.rules and add in there the external domains?
Example:
From: noreply@dmarc.google.com no
From: noreply@dmarc.yahoo.com no

Or do you have anothter alternative to accomplish this?

Thanks in advance.

Best Regards,
Sergio
