how? 90%+ of spam has forged FROM addresses. From crap in my trash from today:

So, it looks like mmm, (check whois) Jeff Martinez should be blocked at buhlgymgagate.us. On the other hand, I look at the headers to one of my posts, and I see that it's coming from, ta-da, 5-cent.us. If I were sending out spam, then you'd be perfectly justified in blocking 5-cent.us.
