Webmail allows you to access your email accounts through a browser such as Firefox, Internet Explorer, or Safari. You can easily access your email account from any computer with an Internet connection and a web browser. On Directadmin, we will provide Roundcube as your webmail client. 

To use webmail:

1. Connect to your webmail, just use your domain:
   1. HTTP: http://www.yourdomain.com/roundcube
   2. HTTPS: https://www.yourdomain.com/roundcube
2. Then you need to provide your username (email address) and password during login. 

The email account will be opened through your browser. The webmail client will then retrieve all read and unread messages associated with your email account.
