SPAMReporter

SPAMReporter is a powerful award winning spam reporting tool that works by analyzing the email header information and determining where the email originated on the Internet. Many spam messages attempt to hide their tracks by forging entries into the header. SPAMReporter checks each line to determine its authenticity and signaling out the actual entry point onto the Internet. Once the entry point is found, SPAMReporter then finds an Abuse contact for the IP owner, and sends an email containing all the evidence and information, in the format they require to suspend or terminate the offending account. SPAMReporter differs from on-line header analyzers and spam filtering programs that report by using a special system folder on your desktop called SPAMDrop. Completely unattended, SPAMReporter will check this folder and processes all messages it contains. This allows you move all your spam from your Inbox to the SPAMDrop folder and let SPAMReporter take care of the rest. Reporting spam to the owner of the IP where the message originated is by far the best way to stop spam on the internet, as most of these IPs are systems with security problems that the Spammer has compromised. SPAMReporter works with any email application that allows the drag and drop messages from the inbox. If your application does not allow this or you are using a webmail application such as Hotmail, SPAMReporter can convert these messages and add them to the SPAMDrop with the Webmail conversion feature. Stopping spam at the source, where it originates, is the only way to eliminate Spam. Filtering is a good idea, but not the answer to spam.
