SpamWeed's refined Bayesian filter is very intelligent when it comes to tell which email is good and which is spam. At the beginning, SpamWeed may make a few mistakes. If it blocks a good email, you can simply go to SpamWeed Administrator Panel and move it to "legitimate mail box". By doing so, SpamWeed learns and improves future filtering accuracy. Usually after a few days' use, it can work completely to your satisfaction.

Some users are interested in only receiving emails from their whitelist contacts while blocking all other emails. By turning on "Only Receive Emails from Whitelisted Senders", the program allows you to do so.
