We are using the Docker image deployment in a Ubutnu VM.
The Ubuntu host has Postfix installed and configured. Is it possible to point Discourse settings in app.yml to the host Postfix?
I tried using localhost as the SMTP host, but I am guessing that is wrong.
Also, do I need to
./launcher rebuild app each time I change a setting in app.yml? It kinda takes a long time.
P.S. We would use SendGrid or Mandrill but we are using Mail List Mode and we will quickly run up a large bill)
