Aggressive Spam Defense can keep your inbox clean by deleting unsolicited emails before they reach your inbox. It comes pre-configured to detect most common spam, and can further learn from your usage, and also easily be customized. An attractive interface allows you to assign weights to each of the detection keywords and phrases. In addition to email content, sender and subject, it can also filter based on the attachment type, allowing you to automatically delete potential email worms before downloading them. The program checks your POP account and displays a color-coded list of your incoming mail, marking all spam in red, good mail in green and all others in yellow. If you want, it can also delete spam automatically, so you don`t have to deal with it at all. You can preview each message, using a safe-preview and then choose to delete it or keep it.
