Todd’s Apps has introduced JunkIt 1.0, their new Mail add-on for Mac OS X. It provides a method for preventing unwanted emails from piling up in your inboxes.

One of its JunkIt’s features is “reverse highlighting,” which is designed to help users focus on their most important emails. The app also comes with some other options, such as junking one-liner emails, specifying a mailbox for clean emails, as well as options for tracking those people who are spamming the most.

A demo version — with all of the functionality of the full version but with reminders that pop up every once in awhile to remind users to purchase the full version — is available at the Todd’s App web site ( Registration is US$18.95.
