>> Turns out emoji domain names score very highly for spam and were going to be blocked to high heaven. I turns out their mailbox.ws domain doesn't have SPF or good DKIM records. Might be part of the problem why google chucks it. Email is a shit show. I feel like getting emails out reliably is akin to black magic now. Without the right incantations your never going to know what happened or why.

Even Google struggles to apply these correctly 100% of the time: google.com TOTAL SPF ALIGNED DKIM ALIGNED 209.85.167.49 3 100% 0% 209.85.218.47 3 100% 100% 209.85.167.43 2 100% 50% 209.85.208.44 2 100% 100% 26 more IPs 28 75% 92.8%

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.
