Enhanced Email Spam Prevention through Sender Verification Dual Models

Spam mails distributed from botnets waste user time and consume resources such as space and network bandwidth. Many works have contribution in spam detection techniques. Mostly, these spam filtering and detection mechanisms are designed to protect the recipients. They do not stop spam spreading out actually. To block the spreading of spam. we design two modules to verify mail sender: Sender Verification (SV) Module and Sender Location Verification (SLV) Module. The first one runs on Mail Submission Agent. It verifies the sender account. The later one runs on Mail Transfer Agent. It verifies spam or ham by considering the sending country location. Since only the mail header is verified in both modules, our approach works well with both text-based spam and other kinds of image spam. Thus, these two separated modules are able to block the spam fast and effectively.
