Read and send email in a web browser

Webmail lets you use a mailbox without installing an email application. Control Center's Open webmail link opens the configured Roundcube sign-in page. It is an ordinary login link: it does not sign you in automatically, create a mailbox, or pass your hosting credentials to Roundcube.

1. In Control Center, open Hosting services → Manage website → Email. Find the intended address and note its Mailbox username. Confirm its status is Enabled.
2. Select Open webmail beside the mailbox, or the service's available webmail link. Confirm that the browser opens the expected HTTPS address. Sign in with the displayed mailbox username and its mailbox password, rather than your customer or hosting-owner login. Roundcube login guide
3. Open Inbox and select a message. Review Junk/Spam, Sent, and Trash if you are looking for a missing message.
4. Compose a short test message to an external email address. Check that the sender address and display name are correct before sending.
5. If the client offers personal settings, adjust the timezone, signature, and preferred display name. Check which sender identities your account is permitted to use; adding a display identity does not authorize an unrelated domain.
6. Review any personal filtering controls carefully. Forwarding, aliases, and advanced mail settings remain in Virtualmin when permitted. If support directs you to a separate Usermin interface, its available features can differ. Usermin overview
7. Sign out when finished, especially on a shared computer. Avoid saving mailbox credentials on a device you do not control.

Check the result: Reply to your test message from the external account and verify it appears in webmail. If a desktop app is configured with IMAP, refresh it and confirm the same folder changes are visible.

Common problems: A missing link can mean webmail is not configured, email is unavailable, or the mailbox is disabled. A certificate warning needs support review. If login works but the inbox is empty, confirm the username and check mail DNS. Record webmail errors and compare with an already configured email app to narrow the issue.

Deleting messages in webmail normally affects the server mailbox and other synchronized devices. Export important messages before clearing folders.
