Do not render "Email to this Page..." menu item when the email server does not support plus addressing
With the latest release there is a "Email to this Page..." menu item for your pages now:
This feature relies on plus addressing. If the incoming email server does not support email addressing then it will not deliver/accept these emails when they are sent.
Either prune the "Email to this Page..." menu item when plus addressing is not supported or implement it to use command tags or some other mechanism to compose the email.
Also, make the rendering of the "Email to this Page..." menu item configurable by the admin. Some sites may not want their users to have "Email to this Page..." in the menu
