Questions and answers regarding the use of Sandboxie with email software. For a longer discussion, see Email Protection.
Q. Why should I use Sandboxie to run my email software?
A. Email software, as any other Internet-facing application, processes data that cannot be completely trusted, as it was received from the Internet. That data -- which is your email -- might contain viruses, and small bits of software designed to exploit vulnerabilities in your email software. By launching your email software under the supervision of Sandboxie, you can confine it to its sandbox, along with any potential viruses and exploits. See Email Protection for more information.
Q. Will Sandboxie identify and delete viruses in my email?
A. No. Sandboxie leaves this task to your anti-virus and anti-malware software. The job of Sandboxie is to provide the first line of defense and prevent a virus from infecting your computer, and potentially even your anti-virus software.
Q. Message SBIE2212 appears when I run my email software in Sandboxie, does this indicate an error?
A. No. As a safety measure, Sandboxie refuses to launch your email software under its supervision, until it is properly configured. For more information, see the reference page for message SBIE2212. To learn how to configure support for your email software, see the next question in this FAQ.
Q. How do I configure Sandboxie for use with my email software?
A. Open Sandbox Settings > Applications > Email Reader and select the email software that you use. If your mailbox data files are not in the default location, see Sandbox Settings > Applications > Folders. Then, you should also test the configuration; see Test Email Configuration.
Q. How do I run my email software under Sandboxie?
A. You can use the Run Email Reader command from the Sandbox Menu or Tray Icon Menu of Sandboxie Control. You can also right-click Run Sandboxed on the executable icon for your email software.
Q. How can I force my email software to always run under Sandboxie?
A. When the software is already running under Sandboxie, go to Program Settings, Page 1, and select the checkbox to Force program to run in this sandbox. You can also use Sandbox Settings > Program Start > Forced Programs to accomplish the same.
Q. My email software is periodically updated (automatically or manually). Will the updates become permanent?
A. No. The updates will be installed in the sandbox and will disappear when the sandbox is deleted. To properly update your software, launch it outside the supervision of Sandboxie, then initiate the update process. If it is already set as a forced program (see previous question), use the Disable Forced Programs command before starting your email software.
Q. Should I create a separate, dedicated sandbox just for email, or can I use the same sandbox for email and web browsing?
A. This depends primarily on your habits. If you want the convenience of opening your email software by clicking an email link (mailto) in your browser, then you have to use (and configure) the same sandbox for both web browsing and email reading. On the other hand, some people prefer to isolate the two unrelated activities into separate sandboxes. There is no strict answer, and both approaches work well.
Q. I want to launch my web browser in a sandbox, but not my email software. When I click an email link (mailto), the web browser tries to launch my email software in the sandbox. What should I do?
A. You can avoid this issue by right-clicking the email link instead of left (normal) clicking it. The right-click menu will let you copy the email address. Then switch to your email software and paste the email address. If the pasted email address begins with a mailto: prefix, then make sure to delete that prefix, including the colon (:).
Q. I want to launch my email software in a different sandbox than my web browser. When I click an email link (mailto), the web browser tries to open my email software in the wrong sandbox. What should I do?
A. See the answer to the previous question.
Q. I have a web mail account and I read my email via my web browser, do I need to configure anything?
A. No, because in this case, none of your emails are stored in your computer.
