The body_modify hook allows modules to make arbitrary changes or transforms to the message body. The provided message should not be modified directly. Instead, the hook should create an io_object representing the new message body and set iop to this value. If, upon entrance to the hook, *iop is not the NULL pointer, it points to a message body modified by another instance of the hook (to allow chaining). If *iop is NULL, no other modules have modified the body and the contents of mess can be used instead. On return from the hook, if *iop is set, the specified io_object will be sent to the remote host instead of the message body present in the spool.
