Hi Everyone,
After a long time running several Toaster server I came back as I found 1 of my toaster server started receiving Spam Emails. I just gone with headers of the spam mails and found spammers are sending mails with proper RDNS, SPF and DKIM mails which is why anti-spam are not marking mail as spams. Please find header of 1 such mail below: Return-Path: <[email protected]> Delivered-To: [email protected] Received: (qmail 8525 invoked by uid 89); 7 Oct 2011 19:52:11 -0000 Received: from unknown (HELO kil9.limitproductions.com) (8.26.89.136) by mail.sujanil.com with SMTP; 7 Oct 2011 19:52:11 -0000 Received-SPF: pass (mail.sujanil.com: SPF record at limitproductions.com designates 8.26.89.136 as permitted sender) DKIM-Signature: v=1; a=rsa-sha1; c=relaxed/relaxed; s=default; d=limitproductions.com; h=Date:Message-ID:Mime-Version:Subject:From:To:Content-type; [email protected]; bh=j2YtklG+XetiShD59Z64C0S+Wgk=; b=kgY45+zYKBfbyQaDqMp0TG4i0jlYtGuqTaigyUwr54qujB8Y4ssznhW5UwWj+VzNANHj32ZhOo wQ TRyTPTkAQhSLb0v7Y8ajK0RqbV5IshyU9VSNh6MatpstX8n2LXHrSm9Qwx/gHS6Is92H5AF1LjoA bXp8dDA6Zd4gAn+B0BY= DomainKey-Signature: a=rsa-sha1; c=nofws; q=dns; s=default; d=limitproductions.com; b=NB2Ar79H0bt0WPGjy8psp1ytlko2yUWyPDj6tsPxyidHBgd6ZXa+hYe5eUD5dgJNTlJU+FSjrT Ht FSVzR71FinDbKVqJRvYWcyNVZ0+SaajGf2EUpFmMO1l9xKWk3YhSIWM+FH/FqFbx8HKYBryyfZvi EE+fPVXDJsPId6mEtoE=; Date: Fri, 7 Oct 2011 15:49:43 -0400 Message-ID: <mzu0owm2nzk3odzinzq2ytq0nwe3mjvjmwu2zwmzn...@kil9.limitproductions.com> Mime-Version: 1.0 Subject: Tired of Feeling Low?

Need everyone suggestion on how to control such emails.
