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.
- **MySQL** — sidebar → **MySQL Management**. Create users and databases there; the **phpMyAdmin** link below it opens an SSO'd phpMyAdmin in a new tab.
- **PostgreSQL** — sidebar → **PostgreSQL**. Same shape as MySQL Management; the **Adminer** link below it opens an SSO'd Adminer.
- **Valkey** — sidebar → **Valkey Cache**. Click **Enable Valkey**, pick a memory cap and mode, and you're done — no password needed because connections are network-isolated to your account.
Mail server hostnames are not per-domain. Your server has one mail server hostname (for example `mail01.cloud-hosting.io`) that handles IMAP, POP3, and SMTP for every domain on that server. Find your exact mail server hostname on the **Dashboard** page in WHP under **Server Information** — that's also where you'll find your server's IP, primary nameservers, and your home directory.
For step-by-step email-client setup, the Email page has a **Setup Instructions** button that lays out the exact host, port, and security settings.
