E-MAIL DETAILS.

Know E-mail Sender's Detail

Friends, after reading this article you'll be able to know,who is sending you the message or the forge mail.

Where Email Comes From
Superficially, it appears that email is passed directly from the sender's machine to the recipient's. Normally, this isn't true; a typical piece of email passes through at least four computers during its lifetime.


This happens because most organizations have a dedicated machine to handle mail, called a "mail server"; it's normally not the same machine that users are looking at when they read their mail. In the common case of an ISP whose users dial in from their home computers, the "client" computer is the user's home machine, and the "server" is some machine that belongs to the ISP. When a user sends mail, she normally composes the message on her own computer, then sends it off to her ISP's mail server. At this point her computer is finished with the job, but the mail server still has to deliver the message. It does this by finding the recipient's mail server, talking to that server and delivering the message. It then sits on that second mail server until the recipient comes along to read his mail, when he retrieves it onto his own computer, normally deleting it from the mail server in the process.


How to know email headers


Steps to open headers for various email clients and services like Outlook, Hotmail, Yahoo, AOL,...


Yahoo Mail
• Log into your Yahoo! Mail account.
• Click the "Options" link on the navigation bar.
• Click the "General Preferences" link.
• Go to the paragraph titled Messages and Locate the Show Headers heading and select "All."
• Click the "Save" button to put your new settings into effect.

  • Gmail
    Log into your Gmail Account

  • open the Email whose headers you want to view

  • Click on the more options link in the message next to the date of the email. If the link says hide options then do not worry u have alreadyclicked on the more options link.

  • Now click the link called show original.

  • This will bring up a new window with headers and the body of the message.


Hotmail
• Log into Hotmail.
• Click on "Options" tab on the top navigation bar.• Click on the "Mail" link on the navigation bar on the left.
• Click on the "Mail Display Settings" link.
• Change the "Message Headers" option to "Full".
• Click the "OK" button.

AOL Mail

If the email is sent from anywhere OTHER then AOL, and you are receiving it in AOL, then open the email you want to trace, or have your client open the email, and look for the link Details. This link is usually just below the To:email in the email message. If the email is sent from an AOL user to another AOL user then our Reverse AOL Screenname search can get you the sender's information.

Outlook Express 4, 5 and 6
Start by opening the message in its own window (or when viewing the message in the preview pane). Then:
With the keyboard:
CTRL-F3 (Message Source Window)
CTRL-A (select all)
CTRL-C (copy)
ALT-F4 (close)
With the mouse:
Click the "File" menu
Click "Properties"
Click the "Details" tab
Click "Message Source"
Highlight, copy and paste everything from this window (Ctrl-A, Ctrl-C)
With viruses, worms and trojans being spread via email, many users now work with the preview screen in Outlook Express turned off. Viewing the contents of email in the preview screen is no different than opening the message. If the email has malicious content, it may execute in the preview screen.

The Importance of Received: Headers

In the above examples ,we've seen that the Received: headers provide a detailed log of a message's history, and so make it possible to draw some conclusions about the origin of a piece of email even when other headers have been forged. This section explores some details associated with these singularly important headers, and in particular how to circumvent common forgery techniques.
Unquestionably, the single most valuable forgery protection in the Received: headers is the information logged by the receiving host from the sender. Recall that the sender can lie about its identity (by putting garbage in its HELO command to the receiver); fortunately, modern mail transfer programs are able to detect such false information and correct it.
