Yes, but fully leagal mail do use encoded headers, such as
this mail. Base64 headers *ARE* standard and in wide use outside
the english-speaking countries. If you really
want to fight spam I suggest SpamAssasin. I use it and even with
a rather high threshold it catches about 75% of my spam.

I block Subject: =?ISO-8859-1? .
All last week, it blocked 5 emails. Every one of them was spam sent via
Yahoo! Groups.
So far this week, it's blocked 3 emails. Yes, all via Yahoo! Groups.
The sky is not falling.
