Sending messages from facebook App to the User

After google search, all most all the posts said it is not allowed to send messages from Facebook App to friends. May be I did not understand completely what the other people are saying about sending messages. Is开发者_JAVA技巧 it allowed to send messages from a facebook app to the user who added the app to his account? (Not to the user's friends)

There are two ways to do it: email and through the application dashboard.

It is not possible to send a mesage to a user's Facebook message inbox from an application.
