If you're a #postmaster (e-mail admin) and struggle with incoming spam, I suggest you increase the SpamAssassin score of all e-mails coming from Gmail, Outlook, Yahoo, Yandex and other popular free mail services.

This is because these services usually have excellent reputation and always pass SPF/DMARC/DKIM checks.

The point is to neuter these score reductions because of compliance, so that if a message contains suspicious words that SpamAssassin dislikes, it's going to get flagged as spam.
