Trying to get discourse up and running I used gmail for the SMTP mentoned in app.yml. A feature of gmail is allowing this according to this article. It doesn’t work. My settings are something like this (I changed my email and pw).
## on initial signup example 'user1@example.com,user2@example.com'
DISCOURSE_DEVELOPER_EMAILS: 'myemail@gmail.com'
## TODO: The domain name this Discourse instance will respond to
DISCOURSE_HOSTNAME: 'localhost'
## TODO: The mailserver this Discourse instance will use
DISCOURSE_SMTP_ADDRESS: smtp.gmail.com
DISCOURSE_SMTP_PORT: 587
DISCOURSE_SMTP_USER_NAME: myemail@gmail.com
DISCOURSE_SMTP_PASSWORD: thepassword
DISCOURSE_SMTP_ENABLE_START_TLS: true
