I'm trying to implement DMARC for a domain and the address specified in the rua tag is my own personal email for convenience. I have been receiving aggregate reports only from a handful of ESPs, and all of them minor ones. Notably, I'm receiving nothing from Gmail, though I know I'm sending thousands of emails to Gmail addresses daily.
Then, I noticed that DMARC inspector complains about the mismatch between the domain and the domain of the rua email. Could this be the cause of the problem? The DMARC specification itself explicitly states that such a mismatch is not forbidden. Google's article on DMARC specifies nothing either way.
If it's not this, what could be the problem?
