My Discourse installation is unable to send emails to my SMTP server. With
discourse-doctor, I have this error when trying to send an email (I have removed sensitive information):
Testing sending to … plain auth. ======================================== ERROR ======================================== UNEXPECTED ERROR 503 AUTH command used when not advertised ====================================== SOLUTION ======================================= This is not a common error. No recommended solution exists!
I would like to change the authentification method from
login. But it does not seem I have a parameter for the authentification method in
app.yml. I am using the Discourse image offered by DigitalOcean.
Can you help me change the authentification method used by SMTP?
