There are possible many forums mapping to the same URL, i.e.,
emacs-devel, tramp-devel, and auctex-devel all map to debbugs.

Well, I've guessed that Rmail is probably not the single one exception
so I went ahead and added a new function which you could

  (add-hook 'rmail-show-message-hook
            #'bug-reference-mode-force-auto-setup)

which should hopefully do what its name and docstring suggest.

It would be awesome if you could test, e.g., by doing the above and

  (add-to-list 'bug-reference-setup-from-mail-alist
             '(nil
               "tsdh@gnu.org"
               "the" ;; just because its surely in every mail
               "http://tsdh.org/%s"))

Then, mails from/to/cc me should have "the" highlighted as bug
references (bug-reference-bug-regexp) and the bug-reference-url-format
should be http://tsdh.org/%s.

When switching to another mail on emacs-devel/debbugs without me, the
url should again be the debbugs one.
