Opening a Dozen Email Boxes? Use Mozilla Thunderbird (and Donate)

If you need to read through a lot of email addresses, try Thunderbird. I’ve had over ten addresses in it, and it works pretty well. It also has an RSS reader that I rarely use, but it’s there. It’s my preferred client, and after a lot of use, I finally donated to the project.
