Free spam monitor

PC Tools Spam Monitor works in the background from your system tray successfully finding junk e-mail  when it comes in your Mailbox. Working with your local black-list, white-list and junk mail filter plug-ins, and also with freely accessible black databases, PC Tools Spam Monitor will identify and tag spam emails before they get to you.
For progressed users, PC Tools Spam Monitor provides a effective collection of customization functions such as plug-in architecture so that fresh junk e-mail filter features can be easily downloaded.
