I just recommended a less painful option for You. If you absolutely gotta have zoho to send emails, try contacting their support as they are the ones who can help with the error code. The recommended email providers do work well for discourse and I don’t see anywhere in the documentation where discourse recommends zoho or google apps for business to send emails.
I did rebuild. And I decided to give elasticemail a try. Now, with elasticemail, I have the rather intriguing problem that email works when test emails are sent with ./discourse-doctor (they arrive in my inbox, receive a 10/10 score at mailtester, etc), but I am not receiving the activation emails when trying to register for the admin account. The logs only say:

However, the email is not being logged in elasticemail at all. Any ideas?
