My pleasure! I am somewhat versed so I’m happy to spread the knowledge where I can 😊 Microsoft does typically set up SPF and DKIM automatically for new accounts, but a small handful of my customers with legacy GoDaddy accounts that got switched to Office 365 found that it wasn’t enabled for them, for some reason. Probably a migration issue at GoDaddy.
Looks like it’s working just fine for your tenant though, and the rest of the test looks good. Pyzor would’ve triggered 'cause it was a short or empty test message - like the tester noted, test with real content to avoid that, but for now we can just ignore the ding, so you effectively have a 10/10. Nice 👌
It’s an unfortunate truth that there is no power on earth that can guarantee you stay out of the spam box. But, your domain and email are in good enough shape that you will pretty much always get delivered, even if sometimes that delivery is to Spam. You (or the person you were emailing) with might be able to harangue the receiving email provider into refactoring their sorting though; I’m sure your recipient doesn’t want their important emails going to spam, either!
