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.

Without SPF and DKIM, I could send messages pretending to be from you to anybody. Average user has no way to know that the "From:" field does not really mean what it says.
