My reconciliation: Spam filtering is very hard. Therefore there are some content based rules and some sender based rules. Google is very good at both of those, which means in this context means accuracy and precision based on content and strictness based on sender. Sender based rules make it hard for spammers to send mail pretending to be from a domain, but does make it harder for anyone to send mail. Hosting your own mail server means hosting the authorization architecture to prove you're not a spammer, which makes it harder. |
