Use webmail

Roundcube webmail lets you read and send email in a browser without configuring an email application first. Open webmail from the OS Cloud panel or through your domain's mail address, for example https://mail.yourdomain.com.

Sign in

1. Open webmail from the OS Cloud panel or visit your domain's mail address.
2. Confirm that the browser shows a valid HTTPS connection.
3. Sign in with your complete email address and the mailbox password.
4. After signing in for the first time, send a test message to an external address and reply to it.

Use webmail safely

• Prefer a personal, up-to-date device.
• Do not allow the browser to save the mailbox password on a shared or public device.
• Sign out after use and close every browser window.
• Do not open unexpected links or attachments before verifying the sender.
• Never share the mailbox password with support.

Troubleshooting

• Sign-in fails: check the complete email address and change the email password if required.
• Webmail does not open: review the DNS and SSL configuration for mail.yourdomain.com, or open webmail from the panel.
• Sending fails: record the exact error and test a message without a large attachment.
• Messages are missing in another app: check whether that app uses IMAP rather than a POP3 configuration that moves messages locally.

For daily use on multiple devices, add the mailbox to an email client or Gmail.
