Webmail (Roundcube)

Accessing Webmail#

Roundcube is available at:

https://YOUR_SERVER:8080

Replace YOUR_SERVER with your server's IP address or hostname. The connection uses HTTPS. If you see a certificate warning on first access, this is because the SSL certificate is issued for your panel domain — you can accept the warning or access webmail through a hostname that matches the certificate.

[!TIP] You can bookmark the direct URL or link to it from your website. The path does not change unless you reconfigure the server.

Logging In#

Use your full email address as the username and your email account password.

Do not use just the local part (e.g. you) — Roundcube requires the full address to identify which domain's account you are accessing.

If your password is incorrect, check:

• You are using the email password, not your Opterius panel password (these are separate)
• Caps Lock is off
• The account exists — see Creating Email Accounts

Interface#

Roundcube provides a full-featured three-pane mail interface:

• Left panel — folder tree (Inbox, Sent, Drafts, Trash, Junk, and any custom folders)
• Middle panel — message list for the selected folder
• Right panel — message preview

The interface is mobile-responsive. On smaller screens the layout shifts to a single-column view, with navigation through the folder list accessible via the menu button.

Composing Mail#

Click Compose to open a new message. Roundcube supports:

• To, Cc, Bcc — address fields with autocomplete from your contacts
• Reply-To — set a different reply address if needed
• HTML and plain text — toggle between rich editor and plain text
• Attachments — drag-and-drop or browse
• Signatures — configured in Settings → Identities
• Spell check — available in the toolbar

Folders#

Roundcube displays all IMAP folders synced from Dovecot. You can:

• Create, rename, and delete folders in Settings → Folders
• Subscribe or unsubscribe from folders (folders hidden from view remain on the server)
• Move and copy messages between folders by dragging or using the right-click context menu

IMAP IDLE — Real-Time Updates#

Roundcube uses IMAP IDLE when supported by the browser connection. This means new messages appear in your inbox automatically without needing to manually refresh. Dovecot has IDLE enabled by default.

[!NOTE] IMAP IDLE works as long as the webmail tab is open and the connection to the server is active. If you close the tab or the network drops, updates resume when you reconnect.

Changing Your Password#

You can change your email account password from within Roundcube:

1. Click the Settings icon (gear, top right).
2. Navigate to Password.
3. Enter your current password and your new password.
4. Save.

This updates the password in Dovecot's user database directly. The change applies to IMAP, POP3, and SMTP submission immediately.
