Redirect all spam to a specific email

[LDB]

I am trying to re-direct all spam to a specific address. So I have,

        rewrite_header From [EMAIL PROTECTED]
        rewrite_header To [EMAIL PROTECTED]

in my config file. But the rewrite ends up looking like,

        From: [EMAIL PROTECTED] ([EMAIL PROTECTED])
        To: [EMAIL PROTECTED] ([EMAIL PROTECTED])


Am I missing something?

Thanks,

LDB
