So something is wrong with your configuration. You can look at the email troubleshooting guide. You don’t have much to go on from that message to be sure. Make sure that the user and password are correct. Make sure that zoho will send from the notification email address you have in system settings.

How do I exactly check that zoho isn’t blocking anything?

You’ll need to check the logs at zoho and /or open a ticket with them

Before opening a support ticket, make sure that Your own setup isn’t the culprit. As far as I know Zoho isn’t a transactional email service provider so they won’t allow you to set up credentials that allow sending on behalf of other users.

You either have to set up email address in the format: or You have to set your email address as the discourse notification email by editing the yml file.


Just wondering if you could possibly look at this particular thread and shed any light!

Looks like you may hold the key to solve this technical problem!

Many thanks in advance.
