How can I determine the MailEnable version from the web interface?

You can determine the MailEnable version by accessing the login page `/mewebmail/Mondo/lang/sys/login.aspx` and viewing the source code for a `?v=` parameter. For example, `v=9.84` corresponds to the version. Alternatively, the version can be obtained via the MailEnableAdmin.msc diagnostic tool. For more details, see the MailEnable Development Guide.
