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)
