I am using a single not-so-complex regexp for the mails that my Berkeley
friends send me.

((re-search-forward "^\\(To\\|[Cc][Cc]\\):.*\\(auluen@\\|beatrice@\\|bentse@\\|blam@\\|bonnieh@\\|burtonl@\\|fchan@\\|yiu@\\|jackchow@\\|jwong@\\|leric@\\|psyeung@\\|sfung@\\|stsf@\\|syang@\\|tonyc@\\|wleung@\\|wwwong@\\).*"
		       nil t)
    (list "Berkeley-HK-Friends"))

It's easy enough for me to add or remove entry in this regexp.

Anyone lisp expert knows the performace trade off btw two cases?
