How can I replace the smtp server installed in discourse?

Hey @bubblylightcyanraft,

Before changing the SMTP settings and Free Mailgun, I’ll recommend checking them to see if they are correct according to Free Mailgun’s documentation.

The SMTP settings can be found following these steps

Navigate to the directory where your app.yml is located.

Open the app.yml file with a text editor like nano or vi. For example: nano app.yml

Find the following lines in the file and update the SMTP server’s details:

DISCOURSE_SMTP_ADDRESS: smtp.mailprovider.com       # change mailprovider.com to your SMTP server
DISCOURSE_SMTP_PORT: 587                           # adjust if your provider uses a different port
DISCOURSE_SMTP_USER_NAME: user@example.com         # your SMTP username
DISCOURSE_SMTP_PASSWORD: a-super-secret-password   # your SMTP password
DISCOURSE_SMTP_ENABLE_START_TLS: true

After you’ve made your changes, save and close the file.

From the /var/discourse directory, rebuild the Discourse container with the command ./launcher rebuild app. This will apply the changes.

Remember to replace the placeholder values with the actual SMTP settings provided by your new email service provider. You can generally find these details in the documentation or settings section of your provider’s website.
