3-dot bullet Who's really sending you that message?

By Linda Link, president of Answer Quest Technologies, Inc.

Just because the e-mail says it came from http://www.Microsoft.com,
http://www.Ebay.com or http://www.AnswerQuest.com doesn't mean it really
did. Email headers can tell the story of how a message came to your
mailbox. Here's how to check that out.

Do NOT open the e-mail. (Outlook 2000 is my example. But all e-mail
software should have a way to view this information). Right-click on the
e-mail you want to check and then click on OPTIONS. At the bottom of this
dialog box you will see INTERNET HEADERS. This is information is what's
important. Here's an example of what a REAL message header from Microsoft
looks like:

Return-Path:
<0_52663_C99372F7-427F-7948-AECC-8F9ED91CF341_US@Newsletters.Microsoft.com>
Received: from delivery.pens.Microsoft.com (delivery.pens.Microsoft.com

You can see that it's from Microsoft... but is it? You can verify this by going to http://ww1.arin.net/whois and type in the IP address associated with the RECEIVED IP address 207.46.248.66 verifying that is really owned by Microsoft. Then it says BY MAIL.NETFOX.NET. This is the company that hosts AnswerQuest.com's website and e-mail.

Here's an e-mail I received asking for me to update my information on http://www.eBay.com. It says it's from users-support29@ebay.com. But is it? Look at the RECEIVED line. It says host35-81.pool80117.interbusiness.it. IT is Italy. So unless eBay has moved to Italy, this isn't real! In the e-mail itself, it had a web link to go to. That web link did NOT go to http://www.eBay.com. It went to an unknown server! This was someone trying to gain information illegally.

In the last few months, I've received probably hundreds of e-mails that BOUNCED back to me (a term that means the e-mail address that the message was addressed to is not active so it returned the message to who was in the REPLY TO field). What's the problem with this? I didn't send them!! Someone out there is sending e-mail messages from webmaster@answerquest.com and a few other e-mail addresses I use. If in doubt, do not reply to the message but instead e-mail the sender directly.

Here are some simple rules to follow:

1. Never give out personal information, credit card numbers, password, etc via e-mail. It is very unsecure! This means that anyone can intercept the message, gather the information and forward it on without anyone's knowledge. Companies like http://www.eBay.com and http://www.Paypal.com will NEVER ask you for information via e-mail.
2. Never open a file that is supposed to be from Microsoft; they NEVER send you attachments. Microsoft will ALWAYS direct you to their website http://windowsupdate.Microsoft.com for updates.
3. Never open file attachments in an e-mail that looks suspicious or if you do not know who is sending it. This is getting MORE difficult because of viruses that pose as e-mail coming from your friends.
4. ALWAYS make sure your Anti-Virus software is up to date (I use http://www.Symantec.com Norton Anti-Virus on all my computers).
5. ALWAYS make sure your Windows is updated by going to http://windowsupdate.microsoft.com for updates.
6. Be careful clicking on a web link in an e-mail. You can be directed to fake websites! A great example is http://www.whitehouse.gov, which is the official White House page, but http://www.whitehouse.net is a spoof. Sometimes people will even go as far as copying the entire site so you cannot tell the difference except the web address.
7. On the same note, ALWAYS be suspicious if an e-mail tells you to go to an IP address instead of a WEB SITE NAME. For example, http://www.answerquest.com uses the IP address 162.33.205.109. Every name you type in is associated with a number. But numbers do NOT have to be associated to a name! Every person who connects to the Internet has a number assigned to them and their ISP's name assigned to it. What does this mean? Instead of going to www.Ebay.com to update your information, you could be going to Joe Doe's home computer where he's collecting people's account passwords for illegal uses!

And finally, let Outlook help protect you. These are important option settings that need to be changed (and I'll explain why).

First, never use the PREVIEW PANE setting. It is possible with the PREVIEW PANE turned on for an e-mail message to run a program script without actually double-clicking to open the message. To turn off the PREVIEW in Outlook 2000, on the Menu toolbar - click on VIEW, click on PREVIEW PANE. Make sure the button for PREVIEW PANE is not chosen. You could leave
AUTOPREVIEW on because this shows a small portion of the message as PLAIN TEXT. It's the ones that come through as web pages with HTML that can run malicious program scripts automatically.

You can also disable other Preview Pane options: on the Menu toolbar - click on TOOLS, click on OPTIONS, and click on OTHER tab. On the bottom of the OTHER dialog box, click on PREVIEW PANE. UNCHECK all 3 options. The first one automatically makes a message that's UNREAD change to READ status when you simply click on it one time. The second option will mark a message as READ when you click onto another e-mail message or arrow up or down off of the selected e-mail message. The third option lets you move through messages easily while using the PREVIEW PANE. Click OK to save your changes.

Another very important option is the TRACKING option; it's usually preset to on. This function will send a reply automatically to anyone who requested confirmation that you received an e-mail. In theory it might be good, but people who just randomly send out unwanted e-mails use this to verify if your e-mail is active. If you left the OPTIONS menu, on the Menu toolbar -
click on TOOLS, click on OPTIONS. Now, click on PREFERENCES, click on E-MAIL OPTIONS. Click on TRACKING OPTIONS. At the very bottom, you want to either select NEVER SEND A RESPONSE or ASK ME BEFORE SENDING A RESPONSE. Click OK three times to exit the OPTIONS dialog box.

Newer versions of Outlook have additional features to help protect you. If you need help feel free to e-mail me.

So, now you are all set to start reading your e-mail!
