If you're experiencing email delivery problems, use these commands to diagnose SMTP configuration issues. For these tests, it supposes that you have a valid .env.production file in your home directory.

bundle exec rake mail:config

TEST_EMAIL_TO=your-email@example.com bundle exec rake mail:test

The test command will:

• Display your SMTP settings (with passwords hidden)
• Show detailed SMTP protocol conversation for debugging
• Attempt to send a test email
• Provide troubleshooting hints if delivery fails

Common issues:

• Authentication method mismatch (try OSEM_SMTP_AUTHENTICATION=login instead of plain)
• SSL certificate verification (try OSEM_SMTP_OPENSSL_VERIFY_MODE=none for testing)

If you're using devbox for development, prefix commands with devbox run:

devbox run bundle exec rake mail:config
devbox run TEST_EMAIL_TO=your-email@example.com bundle exec rake mail:test
