Source Use Bogofilter for better junk detection in Evolution

So you’re using the Linux operating system and you’re not concerned with viruses. But you still get SPAM – and plenty of it. With the Evolution groupware suite you have, by default, Spamassassin as your Junk filtering tool. For some this is enough. For others, howerver, it doesn’t cut it. For those that need more you can give Bogofilter a try. You can use Bogofilter in conjunction with Spamassassin but that setup can become quite cumbersome and will require the creation of filters. To avoid this we will use only Bogofilter and we will train Bogofilter out of the box so it’s working right away to prevent SPAM from reaching you inbox.
With a little preparation this setup will go quickly. Without preparation, it will take some time for Bogofilter to learn SPAM/HAM.
