SMTP Server

DripEmails includes a built-in SMTP server for handling email delivery.

Starting the SMTP Server

Development

# Basic (default port 1025)
python manage.py run_smtp_server

# Custom port
python manage.py run_smtp_server --port 2525

# With debug logging
python manage.py run_smtp_server --debug

# No authentication
python manage.py run_smtp_server --no-auth

Production

Use Supervisord or Systemd for process management. See Production Setup for details.

Configuration

Port Selection

1025: Default (recommended for development, avoids Postfix conflicts)
25: Standard SMTP port (requires root/admin, may conflict with Postfix)
2525: Alternative port (no conflicts)

Authentication

💡 Auto-Disable on Windows

On Windows with DEBUG=True, authentication is automatically disabled for easier development.

python manage.py run_smtp_server --no-auth

# Enable authentication (production)
python manage.py run_smtp_server  # auth enabled by default
