Postfix implements the pipe-to-command interface, This is not
a Postfix invention; many MTAs implement the same interface.
This pipe-to-command interface requires that the sender waits for
the receiver's exit status code.
Besides requiring an exit status code, Postfix also requires that
the receiving program closes stdout as well as stderr.
So you have to queue the message, close stdout and stderr as
inherited from Postfix, and exit (perhaps after fork()).
