; Replaces the class III routines ^XMRPOPA, ^XMRPOPB, ^XMRPOPC,
; which were written by Chiao-Ming Wu, WASH-ISC.
;
; Implements RFC 1939 (replaces RFC 1725)
; Post Office Protocol - Version 3 (POP3) maildrop service
;
; Rather than locking the user's IN basket, which severely disrupts
; mail delivery, we take a snapshot of it, and keep the snapshot in
; a temp global. We then use the temp global during the session.
; Here is the layout of the global:
;
; ^TMP("XM",$J,"POP3")=# msgs^# octets ; total msgs in IN basket
; ; (updated if msgs are deleted)
; ^TMP("XM",$J,"POP3",1)=XMZ^# octets ; msgs 1 thru n are in
