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.

Spam Sleuth

Spam Sleuth monitors your e- mail box behind the scenes and analyzes e- mail messages for spam and virus characteristics. Our program keeps a report of what it finds so that you know why an e-mail has been deemed as spam. . If Spam Sleuth determines an e- mail is spam, it yanks it out of the e-mail server, compresses it so that it takes as little space as possible on your computer, and keeps a report with the suspect e- mail. When your e-mail program gets your e- mail, the spam has already been removed and you can read your e- mail the same way you always have, but without sorting through the junk e-mail to find the gems. Spam Sleuth is the best of the best and gives you control to customize the program to your liking. Spam Sleuth uses a point system to eliminate spam. Spam Sleuth's analyzers: Friends, Spammers,To, Goodwords, Badwords, Profanity, Subject, Attachments, Charsets, HTML Volume, etc. looks at an e- mail a different way and assigns points. The more points an e-mail message receives the more likely it is to be deemed as spam. The less points an e-mail message receives the more likely it is a real gem. E-mail Stamps: You can charge senders a fee to send you e-mail. When Spam Sleuth deems an e-mail message as spam an email sent back to the sender requiring them to pay a fee via PayPal before their message will be sent through to your inbox. (That's right, you make the spammers pay you to send junk e-mail.) Turing Test: Similar to Email stamps, except that you don’t collect money. The turning test sends an email back to the sender and requires them to enter a validation code in order for Spam Sleuth to allow email messages through to your inbox. (Great way to know if you're dealing with a mindless machine or a real human on the other end.) Bayesian Analysis: Looks at your previous e-mail and learns the characteristics of spam and good e-mail. Just like a baby, it needs to be taught right from wrong. By marking your messages as Good or Spam, and the
