Greylisting
This is a revolutionary new method to stop spam. If you combine greylisting with a regular spamfilter, it achieves a success rate of more than 99%. If you choose for greylisting, you need to take into account that some wanted emails can arrive with a delay, especially emails which were sent from someone who has never sent you an email before. Just like with every other spam filter, you take the risk that wanted emails can be stopped.
