In any case, I still contend that simplistic blocking by IP address

reasons.
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.
