Nope, the first 2 Chars in the MID a generated from the UID of the User:
In my Setup the fsf Part is replaced with the name of the current PC.


Here is the Code for this - perhaps you can better finetune the Scoring.


--8<---------------cut here---------------start------------->8---
(defun message-unique-id ()
  ;; Don't use microseconds from (current-time), they may be unsupported.
  ;; Instead we use this randomly inited counter.
  (setq message-unique-id-char
        (% (1+ (or message-unique-id-char
                   (random (ash 1 20))))
           ;; (current-time) returns 16-bit ints,
           ;; and 2^16*25 just fits into 4 digits i base 36.
           (* 25 25)))
  (let ((tm (current-time)))
    (concat
     (if (or (eq system-type 'ms-dos)
             ;; message-number-base36 doesn't handle bigints.
             (floatp (user-uid)))
         (let ((user (downcase (user-login-name))))
           (while (string-match "[^a-z0-9_]" user)
             (aset user (match-beginning 0) ?_))
           user)
       (message-number-base36 (user-uid) -1))
     (message-number-base36 (+ (car tm)
                               (ash (% message-unique-id-char 25) 16)) 4)
     (message-number-base36 (+ (nth 1 tm)
                               (ash (/ message-unique-id-char 25) 16)) 4)
     ;; Append a given name, because while the generated ID is unique
     ;; to this newsreader, other newsreaders might otherwise generate
     ;; the same ID via another algorithm.
     ".warhorse")))
;;   ^^^^^^^^^^

;;   Replace warhorse with the current machine Name (or something else)
