If you setup DMARC reporting, the big providers will send you a daily delivery report for emails from your domain to theirs. Great for tuning deliverability, and for catching ruffians attempting to use your domain.
You're right though, email is still a shit show, it's particularly annoying that they've made so many over-complicated auth schemes based on centralized and insecure-as-a-rule root tech(DNS), and never phase any out. When it's easier to configure postfix than domain identity, you know something is wrong.
