2. Start the "MailPlus Server" from the desktop and in the first step select "Create new email system". Confirm with "Next".
3. Enter the domain name of the email in the "Email system host name" field. The domain name is the part after the "@" of the email. For example, if you have the email address " ", you must enter "test.de" here. Continue with "Next".
4. Now you see an overview with your data. If the data is correct, complete the setup with "Apply".
