Which is why I prefer to set up a tarpit as my high-MX spamtrap, but not make it do anything permanent or even long-lasting. If you're a legitimate sender talking to my tarpit, it'll take you a while to discover that you can't make it through, and you should be able to successfully retransmit at a later time. If you're a spammer, it'll take you a while to discover you can't make it through, but then you probably won't try again.
