Guide Review - Inbox100 4.0 - Spam Filter
This is what Inbox100 does. Mail from approved senders arrives in your Inbox while messages from unknown senders go to a "Quarantine" folder. Now, the idea is to apply Bayesian analysis to the messages in this folder to help you find the good mail from as-yet unknown senders.
Inbox100 inserts the computed spam probability to the message subject so it's easy to sort the list by spaminess. Approving messages is also easy via a toolbar button (Inbox100 also removes the spam score from the subject), but unfortunately the Bayesian filter is so stuck to assigning 99% of spam probability to all mail in the "Quarantine" folder that it is more or less useless.
Inbox100 boils down to a simple whitelisting tool, which it does well, but which isn't a good anti-spam strategy overall.
