Mail-Path
The most effective and easiest way to trace an email is to analyze it's email headers. This can be done by just viewing the full header of received email. A typical email header looks something like this:
"From Barr Thu Jan 3 05:33:26 2008 X-Apparently-To: prasannasherekar@yahoo.co.in via 203.104.16.34; Thu, 03 Jan 2008 05:25:38 +0530 X-YahooFilteredBulk: 189.160.34.89 X-Originating-IP: [189.160.34.89] Return-Path:
"
The above email header gives us the following information about it's origin and path:
a) Sender's email address :- atiles@destatis.de
b) Source IP address :- 141.203.33.92
c) Source mail server :- dsl-189-160-34-89.prod-infinitum.com.mx
d) Email client :- Thunderbird 2.0.0.6
