Discourse – email and Job exception: Net::ReadTimeout



For a Discourse instance to function properly Email must be set up. Use the SMTP_URL env var to set your SMTP address, see sample templates for an example. The Docker image does not contain postfix, exim or another MTA, it was omitted because it is very tricky to set up correctly.

Yah! Discourse doesn’t came with any MTA (mail transfer agent).
I had to install Postfix so that Discourse could send out emails.

My emails weren’t getting delivered…
I was getting the following error on discourse logs(/var/discourse/shared/standalone/log/rails/production.log)….

Job exception: Net::ReadTimeout

After a few tweaks… I got it working…
This is my /var/discourse/containers/app.yml excerpt….

## TODO: List of comma delimited emails that will be made admin and developer
 ## on initial signup example '[email protected],[email protected]'
 DISCOURSE_DEVELOPER_EMAILS: '[email protected]'

## TODO: The SMTP mail server used to validate new accounts and send notifications
 DISCOURSE_SMTP_ADDRESS: mail.domain.com
 DISCOURSE_SMTP_USER_NAME: [email protected]
Rebuild the APP
cd /var/discourse/
./launcher rebuild app
