I m doing and email, using visualforce and i would like to ask you if its possible that the Recipient Type is a field from the masterapplication and not the standard "user, contact, lead", because my user will fill up a field in the master application, where he writes is on email adress , and after i want to send email to tthis email adress in the masterapplication, but is not a user, contact or lead.
Thank u!
