Google has started automatically blocking emails sent by bulk senders who don't meet stricter spam thresholds and authenticate their messages as required by new guidelines to strengthen defenses against spam and phishing attacks.

As announced in October, the company now requires those who want to dispatch over 5,000 messages daily to Gmail accounts to set up SPF/DKIM and DMARC email authentication for their domains.

Meanwhile, Microsoft's Exchange platform blatantly ignores DMARC failures for senders and relays on its "Good PTR list". Bit of a glaringly large hole for spam to pass through.

Don't forget that Microsoft will also process forwarding rules before it finishes the "is this bad" scan.
