	And what is the error message ?
		"Mail to file disallowed w/o proper privileges"

	That behaviour comes from having recipient privilege of "nobody",
	which is a pariah user that is not allowed to do certain things,
	like write to any file.

	Within the mailbox.c there is one instance of "TO_FILE:" tag.
	I added following explicite code on it:

	case TO_FILE:		/* append to file */

	  /* Solaris has "interesting" /dev/null -- it is a symlink
	     to the actual device.. So lets just use that magic
	     name and create a FAST "write" to  /dev/null..  */
	  if (strcmp(usernam,"/dev/null") == 0) {
	    notaryreport(rp->addr->user,"delivery",
			 "2.2.0 (delivery successfull)",
			 "x-local; 250 (Delivered successfully)");
	    DIAGNOSTIC(rp, usernam, EX_OK, "Ok", 0);
	    return;
	  }

	This is actually copied (with small edit) from about 170 lines
	further down, and this will now likely obsolete that latter
	instance..

	This explicite test for "/dev/null" target is done before
	analysis of user privilege, and thus "allow" writing to /dev/null.
