    Somehow no emails are being send. I keep on getting the same error:

    “535 Authentication Failed”

    Today added two way authentification on zoho email, but after I received this error disabled my two way authentification settings, but the error is still here.

    Hi @rookas,

    This is an extract from your session transcript, not diagnostics log.

    If you go into Post SMTP > Post SMTP, then on the right hand section you will find Diagnostic Test under the heading Troubleshooting.

    Hi @rookas,

    Thank you – that’s helpful. Have you tried creating an App-specific Password in Zoho?

    Hi @rookas,

    Can you try changing the Authentication from ‘Plain’ to ‘Login’ in Post SMTP settings?

    Kind Regards,
    Tim
