Some Additional Security Settings

pictogram_thunderbird_2.jpgThunderbird provides additional security measures to protect you from junk mail, identity theft, viruses (with the help of your anti-virus software, of course), intellectual property theft, and malicious web sites.

We will look at the following Thunderbird security features. First a little background on why you need to consider some of these measures:

  • Adaptive junk mail controls
    Adaptive junk mail controls allow you to train Thunderbird to identify junk email (SPAM) and remove it from your inbox. You can also mark messages as junk mail manually if your email provider's system misses the junk mail and lets it go through.
  • Integration with anti-virus software
    If your anti-virus software supports Thunderbird, you can use that software to quarantine messages that contain viruses or other malicious content. If you're wondering what anti-virus software works with Thunderbird, you can find a list here: http://kb.mozillazine.org/Antivirus_software.
  • Master password
    For your convenience, you can have Thunderbird remember each of your individual passwords of your e-mail accounts. You can specify a master password that you enter each time you start Thunderbird. This will enable Thunderbird to open all your email accounts with your saved passwords.
  • Restrictions on cookies
    Some blogs and websites attempt to send cookies (a piece of text that stores information from Web sites on your computer) with their RSS feeds. These cookies are often used by content providers to provide targeted advertising. Thunderbird rejects cookies by default, but you can configure Thunderbird to accept some or all cookies.

In the Security Preferences section of Thunderbird's Options/Preferences dialog box you can set up the preferences for these features.

  • In Windows and Mac OS X, go to the 'Tools' menu and click 'Options'.
  • On Ubuntu or other versions of Linux, go to the 'Edit' menu and click 'Preferences'.
