If anyone is thinking of doing that sort of thing, I would recommend putting a fast host in front of the slow one. We do that at work, and it works well.

Our fast host rejects most spam, quickly about it, and forwards mail locally via LMTP. The LMTP server may take an awfully long time to accept mail, but that isn't a problem, because we've configured its only client to be generous about timeouts.

But, in effect, that's an 'accept and bounce later' system.

Everyone here seems to be saying that's a bad thing :) (faked sender email addresses etc)

Surely, if you're going to be able to reject a message at any time, you should do it at the initial entry point so that faked sender email addresses have less impact.
