Roundcube webmail lets you read and send email from a browser.

Open webmail.yourdomain.com, replacing yourdomain.com with your real domain name. For example, if your domain is example.com, use webmail.example.com.

Log in using the full email address and mailbox password. The username should look like name@example.com, not only name.

CyberPanel normally creates the webmail hostname when the domain/mail hosting is provisioned. If webmail.yourdomain.com does not open, contact support so we can check the webmail vhost, DNS, and SSL certificate.

If login fails, check that the mailbox exists, the password is correct, and the domain's MX records point to the correct mail service.
