There are a few threads about it, and it’s very straightforward, but you need to understand the basics (and write in English if possible).

That’s the Discourse AI reply for your question:

To configure e-mail on a self-hosted Discourse site, you’ll need to set up and verify your SMTP settings. This is crucial for user signups, notifications, and account recovery.

Here’s a step-by-step overview:

1. Configure SMTP settings:

• Discourse sends mail via SMTP; common providers include Mailgun, SendGrid, Amazon SES, and others.
• You’ll typically configure these values:
  • DISCOURSE_SMTP_ADDRESS (SMTP server address, e.g. smtp.mailgun.org)
  • DISCOURSE_SMTP_PORT (commonly 587 or 2525)
  • DISCOURSE_SMTP_USER_NAME (your SMTP login)
  • DISCOURSE_SMTP_PASSWORD (your SMTP password)
  • Optional: DISCOURSE_SMTP_ENABLE_START_TLS for enabling TLS
  • Optional: DISCOURSE_SMTP_DOMAIN

2. Edit your configuration:

• You do this in your container’s app.yml file (/var/discourse/containers/app.yml).
• Look for the env: section and fill in the variables above.

3. Rebuild your container:

cd /var/discourse
./launcher rebuild app

2. Test your setup:

• Try signing up as a new user, or use the Rails console to send a test email.
• If emails aren’t received, check your mail provider logs and review Discourse logs via /logs.

3. Troubleshoot common problems:

• Wrong credentials, ports, or lack of TLS are common culprits.
• Some providers (like Gmail) require “App Passwords” or have strict security.
• SMTP services may block emails if SPF/DKIM/DNS records are not configured.

4. Best practices:

• Always use an authenticated, reputable SMTP relay.
• Configure SPF/DKIM records for your sending domain to avoid spam.
• Do not use personal mailbox SMTP (like Gmail) for production.
