1. SpamBayes

SpamBayes Outlook PluginSpamBayes Outlook PluginSpamBayes Outlook Plugin

SpamBayes is a Bayesian anti-spam plugin for Microsoft Outlook that "tightly integrates classification and training into the Outlook interface."

In layman's terms, it tries to classify your incoming messages into different categories—spam, good, and unsure. After it classifies each incoming email, it automatically places them in each corresponding folder; thus, you're spared from reading those pesky emails.

Being Bayesian, it learns from the contents of spam and good email to calculate the probability of a message being good or spam. Basically, it observes your behavior—what emails do you consider good emails and what emails do you label spam. Then, it analyzes those piles of emails, searching for clues why these emails are different.

For example, the word "Nigeria" or the phrases "lose weight fast" and "lottery" often appear in spam emails. SpamBayes remember this and even when the spam changes, the plugin adapts with the changes.

SpamBayes work with Outlook 2010 (Windows 7), Outlook 2000/2003/ 2007/2010 (Windows XP/Vista), Outlook Express (Windows XP). If you're using Windows 7 and it seems like SpamBayes doesn't work, installing it in C:\SpamBayes will do the trick.

2. Send Secure

Instead of the regular Send button, you can use the Send Secure Outlook add-in to securely send your message to anyone through the EdgeWave (the creator of the plugin) gateway. After that, the message is forwarded to the encryption system which, in turn, notifies the receiver to pick up the message through a web interface.

When downloading the installer, save it locally and then run it. Make sure to check the certificate and close Outlook before installing it. Once you launch the installer, there will be a step-by-step instruction what you should do when you launch it. You'll see the Send Secure button above the Send button in Outlook.

Send Secure is compatible with Windows 7 and 8, 32 and 64 bit as well as with Outlook Versions 2007, 2010, 2013 and 2016.
