At your service:

--8<---------------cut here---------------start------------->8---
(defvar ambrevar/known-mailing-list-archives
  '(("help-guix@gnu.org" . "guix-user")
    ("guix-devel@gnu.org" . "guix-devel")
    ("guix-bugs" . "guix-bugs")
    ("guix-patches" . "guix-patches"))
  "Alist of mail adresses and their Yhetil name.")

(defun ambrevar/guess-yhetil-link (message-id)

    (when mailing-list

              mailing-list "/" message-id))))

I had to create an alist to map between the address of the mailing list
and the Yhetil name because in the case of guix-user, the address is not
the same (help-guix).  I wonder why.

Cheers!
