An advantage to setting up your mail program, such as Outlook, to view text only, no HTML, is that you can more easily spot fraudulent emails.
I received an email that said it was from Bank of America, but since I always view the text version, I saw that the email was really from:
From: “Bank of America”<firstname.lastname@example.org>
Subject: [Norton AntiSpam]Alert: Account Resolution Required
Date: Mon, 14 Jun 2010 05:10:09 +0100
And I’m pretty sure that Bank of America’s webmaster isn’t in Germany (.de).
NEVER ever click a link in an email from a financial institution or any company that has your financial or credit card information. Always go to a website directly by typing the URL in the Address bar of your browser.
