I wrote about this last year, but I feel it's still relevant. Spam filters, especially Google and Microsoft's (whose e-mail servers don't play by any of the standard rules nor do they send DMARC reports), are horrible over aggressive.
I have seen more phishing/ransomware e-mails come through mine (lots of malicious Javascript made to look like Excel files), so I can understand how great the risk is. The fact still remains though. E-mail is broken and is less reliable than an envelop dropped in a letterbox.

I don't know about Microsoft, but I get a couple of DMARC reports per day from Google's email infrastructure. I also get reports from aol.com, yahoo.com, linkedin.com, comcast.com, fastmail.com, etc.
