Yes, I saw you used this kind of trick. It seems very interesting.

However, I wonder if it's really useful to answer with a defer to the incoming spambot. I mean, you could also put an ip address as an higher MX knowing that this address doesn't listen on port 25, that should also work and consume less resources. And this would also work for people being limited to only one IP for their mail server. What do you think?
