How to Prevent Others From Accessing Your Emails
If you use an email program like Outlook or Eudora chances are all your email, sent and received, can be accessed by anyone you share a computer with. If you want to keep those emails private, there are several things you can do.
Double Delete Sensitive Emails: You can delete certain emails in your "in box" or "sent" email folder but that does not mean they've been deleted from your computer. Often, they are simply placed in your "deleted items" folder until deleted later. Make sure that you double delete sensitive emails by going into your deleted items folder and deleting the sensitive emails once again.
Use Web-Based Email Services: A good way to keep others who you share a computer with from accessing your email is to use Web-based email services. Web-based email stores your email on a computer server like a Web page and not on your own computer. To prevent others from accessing your Web-based email keep your password to yourself.
