Here out the outtakes of my edits.  Sorry I can't send something
cleaner since we have a bunch of other irrelevant edits.

OK.  Here's the change to MMAILBOX.  string MYNAME is set to be
the official local host name (code not included).  All changes
in NICSW

;;; Canonicalize address
;;; Entry: STRBUF/ address from file
;;; Call: CALL CANADR
;;; Returns: +1
;;;	    E/ host name,,user name
;;; host name of FILHST is special, means destination is indirect file
FILHST==777777
CANADR:	SAVEAC <A,B,C>
	STKVAR <HSTPTR>
	HRRZ E,N		;Save start of name (will be copied here)
	MOVE A,[POINT 7,STRBUF]
	SETZ B,			;Where host pointer will be if any
	DO.
	  ILDB C,A
	  IFN. C
	    CAIN C,"@"
	     MOVE B,A		;Save pointer to last @
	    LOOP.
	  ENDIF.
	ENDDO.
	IFE. B			;If no host name, copy string and return
	  SAVEAC <T,TT>
	  MOVEI T,STRBUF	;Is this name in hash table?
	  CALL HSHLUK		;Well?
	   JRST CPYSTR		;No, just copy it then
	  HRRZ E,(I)		;Yes, use that value
	  RET
	ENDIF.
	CAME B,[POINT 7,STRBUF,6] ;Was the @ the first character?
	IFSKP.
	  HRLI E,FILHST		;Yes, local address indirect file
	  CALL CPYSTR
	ELSE.
	  SETZ C,		;Foreign address
	  DPB C,B		;Replace @ with null
	  CALL CPYSTR		;Copy the name
	  MOVEM B,HSTPTR
IFE NICSW,<
	  MOVE A,HSTPTR		;Get pointer to host

	    HRROI A,HSTTMP	;Store local name in scratch area
	    SETO B,		;Local host address for this protocol
	    CALL MYADDR		;Get local host address for this protocol
	    IFSKP.
	      CAMN B,HSTADR	;Is this our local host?
	       RET		;Yes, don't need host name
	    ENDIF.
	  ENDIF.

IFN NICSW,<
	  HRROI A,MYNAME
	  STCMP%	 
	  SKIPE A		;us, don't need host name
	   TXNE A,SC%SUB	;.#domain stuff? (this might not be needed???)
	    RET			;yep, us again
>;IFN NICSW
	  HRL E,N
	  MOVE A,HSTPTR		;Start of host name
	  HRLI N,(<POINT 7,0>)
	  DO.
	    ILDB B,A
	    IDPB B,N
	    JUMPN B,TOP.
	  ENDDO.
	  MOVEI N,1(N)		;Update free pointer
	ENDIF.
	RET

Here's the change to MMAILR:  Just the FWDRCP routine.

Here's the changes to MM.   I added this flag called F%VRFY.
SEND and REPLY set the flag off.  Two new commands (VSEND/VREPLY)
set the flag on for people who have important mail or whatever.
This might be better done with an MM set variable or something.
