notify/direct-smtp: customer contacts refused; an address taken from a Customer, HeadOffice, Vendor or User record needs read rights on that type (a contact's user record: User or Customer rights). Staff may still give any address (report scripts use it). The delivery-on check runs after these. notify/direct-message: customer contacts and subcontractors refused, as the client already hides it from them. F3 and F4 fixed.
