Use these hostnames from inside your WHP container — they resolve to the internal services your site can talk to. They don't work from your laptop; see the note below.

<Hostnames />

## Where do I get credentials?

Each service's credentials live in a different section of the WHP panel:

- **MySQL** → **Databases → MySQL → Users**
- **PostgreSQL** → **Databases → PostgreSQL** (if enabled on your plan)
- **Redis** → **Caching → Redis**
- **Memcached** — no auth required; the service is isolated per container.

## Mail servers

Mail server hostnames are **per-domain**, not a single shared hostname. Find the exact IMAP / POP3 / SMTP hostnames for each domain on the **Dashboard** page in WHP.

## Connecting from your laptop

Direct external connections to these internal services are not exposed for security reasons. Use the panel's tools instead:

- **MySQL** — **phpMyAdmin** in the panel for ad-hoc queries.
- **PostgreSQL** — **Adminer** in the panel.
- **Redis / Memcached** — use the **Caching** section's built-in CLI panel.
