I will contend that there cannot be a content filter that can  
reliably separate spam from non spam. Any non-spam message received  
by one person would be spam if it were sent to 10 million harvested  
addresses. OTOH, taking the definition of spam as Unsolicited Bulk  
Email makes detecting a spamming IP address almost trivial. The trick  
is to stop accepting mail from that IP address only until it has  
cleaned up. Once the spam is gone there is no need to block the  
address unless it has proven to be a repeat offender without an  
effective process for shutting the spammers down.
