Unfortunately, many of the spammers are moving those silly codes closer to
the text of the subject (or even ahead of it). We still mark lots of spam
and some non-spam with the test, though (we look for a few characters after
a run of spaces...where the spammers have caused "few" to shrink, along
with the size of "run"). It's up to the users whether to pay attention to
the header we add.
