Facebook "Send me an email" permission

I prompted for the "email" permission in my Facebook application. However,开发者_如何学运维 when I access the graph api of the user, there is no field called "email" available even though I know they have an email on Facebook. Why?

As far as I know based on my experience with their API, Facebook does not offer access to the messaging framework, therefore you are not allowed to send messages on a user's behalf.

Is this for a test user where you know they accepted the permissions prompt and have an email?

How are you trying to get the email? I get them via FQL:

SELECT first_name, last_name, email from user where uid = {userid}
