|MailBeeLicenseException||MailBee.NET Security Powerup not licensed.|
This overload requires the license key be already set (such as with MailBee.Global.LicenseKey property, app.config, web.config, or in Windows registry).
This class on its own does not have any useful features. It mainly supports the licensing infrastructure. For instance, it lets you check how many days you still have in trial mode.
