// optionally these fields are also accepted
type, // string of the file mime type
name, // name to give the file as perceived by the recipient
charset, // charset to encode attatchment in
method, // method to send attachment as (used by calendar invites)
alternative, // if true, will be attached inline as an alternative (also defaults type='text/html')
