I have not tried doing this before but if I were to try I would first
create duplicate model classes for the models needing a different
primary key defined. There should be no reason why two model classes
point to the same db table except that it seems weird.
class ContactEmail extends AppModel {
var $tableName = 'contacts';
var $primaryKey = 'emailAddress';
var $belongTo = ...
}
And override the various fields as needed and ditto for the
MailMessage if needed.
YMMV ....
