So just setup Discourse on a DigitalOcean droplet (1gb ram).  
Using Zoho for the mail system.

I have the SMTP set in the app.yml:

## TODO: The SMTP mail server used to validate new accounts and send notifications

DISCOURSE\_SMTP\_ADDRESS: [smtp.zoho.com](http://smtp.zoho.com)  
DISCOURSE\_SMTP\_PORT: 587  
DISCOURSE\_SMTP\_USER\_NAME: [noreply@essenceofzen.org](mailto:noreply@essenceofzen.org)  
DISCOURSE\_SMTP\_PASSWORD: “\*\*\*”  
DISCOURSE\_SMTP\_ENABLE\_START\_TLS: true

I have DKIM and SPF set, and I still cannot get the “send test email” function to work and logs via sidekiq states:

Jobs::CriticalUserEmail

{“type”=\>“signup”, “user\_id”=\>1, “email\_token”=\>“dd889903f2ffa1f6b8dc9f7f99ac3f19”, “current\_site\_id”=\>“default”}

Jobs::HandledExceptionWrapper: Wrapped Net::SMTPAuthenticationError: 535 Authentication Failed

any advice?
