We talked about how e-mail blacklists and whitelists work last time. A receiving e-mail system interrogates one or more existing databases to determine whether the e-mail sender's IP address matches that of a known spammer or a known "good guy." If there's a match, the receiving system often makes the delivery decision based on that match. It rejects the e-mail in the case of a blacklist or delivers it in the case of a whitelist.

Today, we'll focus on blacklists. First and foremost: beginning a conversation with "What gives you the right...?!" is guaranteed not to have the desired effect.
