/* SYNOPSIS
/*	#include <recipient_list.h>
/* DESCRIPTION
/* .nf

 /*
  * Information about a recipient is kept in this structure. The file offset
  * tells us the position of the REC_TYPE_RCPT byte in the message queue
  * file, This byte is replaced by REC_TYPE_DONE when the delivery status to
  * that recipient is established.
  *
  * Rather than bothering with subclasses that extend this structure with
  * application-specific fields we just add them here.
