Spam assistant issue

[sojic]

Is it possible to configure mail server like this:

If somebody send mail to user@server.com, mail server will return him message: "If you are human reply to this message".

When sender will reply to the message, we know that it is not spam. It should happens only once, for first mail.

If it is not good scenario...

Is it possible spam messages to be stored in spam folder (server side)?
