We do not need your list of mailboxes to configure email backup. The Mail Bagging setup is very simple on your end, and should only take you a few minutes. All you have to do is to add our mail server as the lowest priority to your MX records. The full instructions are sent to you after signup.
If you choose additional solutions with your Mail Bagging service, such as Email Defense and/or Email Continuity, individual mail boxes may need to be configured. If you will require assistance or have additional questions, please contact a Webservio Customer Care Representative.
