// Add message to a folder. Each mail account is expected to create a
// subclass of mail::addMessage. A mail::addMessage object gets created by
// mail::folder::addMessage(). This superclass provides fields, initialized
// with defaults. The fields may be changed at any time before invoking the
// go() method. The message text is provided by calling saveMessageContents().
// saveMessageContents() may be called repeatedly to provide the contents of
// a large message in pieces. The message is saved by the go() method.
// The process may be aborted at any time, prior to go(), by invoking fail(),
// which automatically destroys the mail::addMessage object.
//
// A failure occuring while trying to add the message (including invoking
// fail()) is reported by the callback's fail method (the subclass receives
// the callback object and is responsible for dispatching the proper
// notification).
