nnmail-split-fancy was designed to solve just this problem

(setq nnmail-split-methods 'nnmail-split-fancy)
(setq nnmail-split-fancy
      '(|
        ("from\\|b?cc"    "foo@bar"  ; match from, cc, bcc
         (|
          ( "subject"     "BAZ"     "mail.foo-bar.baz")
          ( "subject"     "QUUX"    "mail.foo-bar.quux" )
          "mail.foo-bar"))
        ;; more splits here
        ;; ...
        ;; The last entry is the catch-all group for mails
        ;; which haven't matched any other rules
        "mail.everything.else"
        ))
