Thank you for spending your efforts creating the tutorial!
I have a suggestion, if you can spare some more time, how about writing some advance tutorial about setting up SPF, DKIM, and DMARC for Yandex as well?
Because, I think, at least without SPF and DKIM, the email might end up in spam (or worst case, outright refused by receiver’s email service).
As personal experience, in the setting of Yandex, they only require to set DKIM. After sometime, I heard of SPF, I had to google to know how to set Yandex’s SPF. And only until recently, I learnt about DMARC. And google again to know how to set it up.
And, hope that it’s not too much out of topic, just a question, does anybody have problem with Captcha during registration?
I already have my own account, so I’m good. But I can’t register for my friend. Clear cache, clear cookies, try different machines (desktop, laptop, mobile), different network (home, work, internet cafe, mobile, VPN). Nothing work. Either “wrong Captcha”, or if with phone number: “SMS limit”.
