In upcoming sections, we will be using Mozilla's Thunderbird e-mail program to show you how to configure your e-mail client for maximum security. Similar to Mozilla's Firefox browser, Thunderbird has many security advantages over its counterparts like Apple Mail and Outlook.
Thunderbird is a so-called "mail user agent" (MUA). This is different from web-based e-mail services like Google's Gmail. You must install the Thunderbird application on your computer. Thunderbird has a nice interface and features that enable you to manage multiple mailboxes, organize messages into folders, and search through mails easily.
Thunderbird can be configured to work with your existing e-mail account, whether that account is through your Internet Service Provider (such as Comcast) or through an web-based email provider (such as Gmail).
Using Thunderbird has many advantages over using web-based e-mail interfaces. These will be discussed in the following chapter. To summarize, though, Thunderbird enables much greater privacy and security than web-based e-mail services.
