bounce spam

I have an email gateway setup with fetchmail and it works great. spamassassin is also VERY accurate. I get a few false positives and a few spams that make it through but it's rare. So I'd like to know how I can

1) Delete mail that is spam
2) Bounce it, in case it happens to be legit.

For the bounce, I would not want to include the actual spam assassin results, but just the email itself, that way if a spammer actually used a valid return address, he would not know what made it spam. But this is not a big issue since I can always turn off the feature in spam assassin, since I won't be getting spam mail anymore anyway.

So how would I manage to do this, delete and bounce spam? Thanks.

There's no point in bouncing spam: spammers never use a valid return address and bouncing just gets the traffic heavier. Most msg will go off to some poor guy who has nothing to do with it and you'll end up being a spammer yourself :-\

As for deleting spam, i suppose you mua can filter emails with a X-Spam header.
Or you could install procmail and send spam to /dev/null if you're not afraid about false positives.

Anyway, procmail can bounce too.

Yeah I figured procmail could do that, but I just need to know how. I want to bounce it that way if I do get a false positive at least the person will know and ether try again or contact me a different way.

But there's an option to foward mail, so if I make an account and make the home /dev/null and make it foward to that account it will work? I heard the /dev/null in jokes and stuff but never knew it actually worked.
