Greylisting is great. The day that I implemented it I saw a 90% reduction in spam.

It's really minimal and it only adds the delay to the first message between users. I never get complaints about the delay. > One downside is that I guess the entire email needs to received and This is a huge downside especially with the size of some of these attachments. If you can block it before it fills your pipe you soften any effect that the greylisting delay adds. Don't forget about postscreen as well. It's easy to apply and does a great job. -- D'Arcy J.M.
