If you live in the US, you are probably getting spam from the rest of the world. (Why do they hate us??!)
I noticed an uptick of spam email from China in the last couple of years. Recently I figured out a quick trick to block email containing Chinese characters.
If you are familiar with email headers, you might already know that there's a header that normally looks something like this:
Content-Type: text/html; charset="UTF-8"
Email with Chinese language characters might have a header like this:
Content-Type: text/html; charset="gb2312"
So in your email program, simply add a new spam filter to exclude email containing headers with the text above, by matching the text charset="gb2312".
Hope this helps you cut down on junk mail...
