Is there a way to change the email address used for email notifications for existing users? If the system that goes down is our own mail server (we manage our own email servers), then we would not be receiving those alert emails being sent to it (it just happened today... didn't think about this when setting up the system.

I know we can add new users with a different email email (ex @mac.com), but it would be simpler if we can edit the email for the existing ones.

Thanks,

Roberto
