no, the email address is not JMP dependent. It can be anything you want.
The permissions are provided by your email client.
A long time ago I was somewhere where the email client didn't require permissions. In the second meeting where several people were blackberrying instead of listening, I clicked a script button that sent them 100 emails at 15 sec intervals, a special version of the "ping of death", the next day the admin had that one locked down.
