Email service can be disabled or enabled using this tool. If you do not use DiscountASP.NET for your email service, we recommend that you disable email service in order to avoid any potential problems.
Disabling your email immediately removes all of your existing email accounts from the server. We cannot recover any messages or configuration after email is disabled, so it is important that you are sure that you no longer need email service if you choose to disable.
Enabling email service will create the default Domain Administrator account, postmaster@YourHostedDomainName.com, and also reset all DNS setting to the new account defaults. If you have any custom MX settings in your DNS, they will have to be recreated after enabling email.
