This conversation is getting rather OT for -stable, but I felt the need to ask a question: To defeat this, wouldn't a spammer just have to send out the same spam twice in a row from the same machines, spaced apart by a little time? Bonus for the spammer: accounts on servers without greylisting would get two copies of the spam. Greylisting is a decent idea, but it seems to me that it's just another tool in the ongoing arms race against spammers. It may work for a while, but eventually they'll catch on and it will only cause unnecessary delays for legitimate mail.
