Evolution is a great e-mail client. It has some ways to make it easier for you to setup filters as well. For example, if you've already received email from a list, you can right-click on the message and select "Create rule from message -> Create rule for mailing list".
The best way to learn is by poking around and see what rules work best for you- everyone has their own preferences.
