AFIK, from the Sieve RFC draft[1], strings compare case-insensitive when 
no :comparator argument is given in the action, so I really don't known 
what is wrong, you could try to force the comparator, eg:


   if header
     :comparator "i;ascii-casemap"
     :contains
       ["To", "Cc", "Bcc", "Reply-To", "In-Reply-To"]
       [
         "mailer-daemon at one.example.com",
         "mailer-daemon at two.example.com",
         "mailer-daemon at three.example.com"
       ] {
     fileinto "mailer-daemon";
     stop;
   }


Though, here, it works fine with(out) it.

Instead of ":contains" you can use ":matches", eg:

   if header :matches "to" "mailer-daemon@*" {...}
