Thanks.  I tried the following: I inserted this expression into a buffer
(*scratch* and a buffer in fundamental mode):

#+begin_src emacs-lisp
(("subject" ("^xxx .*" 100 nil r))
 ("from" ("\"name\" <email>" 10000 nil e)
  ("\"name\" <email>" 10000 nil e) ("\"name\" <email>" 10000 nil e)
  ("\"name\" <email>" 10000 nil e) ("\"name\" <email>" 10000 nil e)
  ("\"name\" <email>" 10000 nil e) ("\"name\" <email>" 10000 nil e)
  ("\"name\" <email>" 10000 nil e) ("\"name\" <email>" 10000 nil e)
  ("\"name\" <email>" 10000 nil e) ("\"name\" <email>" 10000 nil e)
  ("\"name\" <email>" 10000 nil e) ("\"name\" <email>" 10000 nil e)
  ("\"name\" <email>" 10000 nil e) ("\"name\" <email>" 10000 nil e)
  ("\"name\" <email>" 10000 nil e) ("\"name\" <email>" 10000 nil e)
  ("\"name\" <email>" 10000 nil e) ("\"name\" <email>" 10000 nil e)
  ("\"name\" <email>" 10000 nil e) ("\"name\" <email>" 10000 nil e)
  ("\"name\" <email>" 10000 nil e) ("\"name\" <email>" 10000 nil e)
  ("\"name\" <email>" 10000 nil e) ("\"name\" <email>" 10000 nil e)
  ("\"name\" <email>" 10000 nil e) ("\"name\" <email>" 10000 nil e)
  ("\"name\" <email>" 10000 nil e) ("\"name\" <email>" 10000 nil e)
  ("\"name\" <email>" 10000 nil e) ("\"name\" <email>" 10000 nil e)
  ("\"name\" <email>" 10000 nil e) ("\"name\" <email>" 10000 nil e)
  ("\"name\" <email>" 10000 nil e) ("\"name\" <email>" 10000 nil e)
  ("\"name\" <email>" 10000 nil e) ("\"name\" <email>" 10000 nil e)
  ("\"name\" <email>" 10000 nil e) ("\"name\" <email>" 10000 nil e)
  ("\"name\" <email>" 10000 nil e) ("\"name\" <email>" 10000 nil e)
  ("\"name\" <email>" 10000 nil e) ("name <email>" -1000 nil e)))
#+end_src

then I replaced all line breaks with spaces and called M-:
(pp-fill (point-min) (point-max)).  But that succeeds almost
immediately...   Not sure what the important different aspect in your
scenario is.

Have you tried to change the value of `pp-default-function' btw?

Thx,

Michael.
