  • Pre-configured to use PostgreSQL (recommended for production).

• SSL support out of the box.

• Adminer administration frontend for PostgreSQL (listening on port 12322 - uses SSL).

• Postfix MTA (bound to localhost) to allow sending of email (e.g., password recovery).

• Webmin modules for configuring Postfix, PostgreSQL.
