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@*" {...}
