i want to know from which ipaddress a email is comming to me,is it possible to know,and how can we know tht?

Answer 1

If you are using Outlook (ex for office 2003) and you want the sender's IP not the mail server do the following:
-Double click the message to open it
-Click view on the menu bar
-Select Options
-Look in the Internet Headers Box

What you will be attempting to locate is
Received: from Username (this is usually the sender's name)
(XXX-XXX-XXX-XXX.server. citylocation .State .Prefix. domain. Extension [XXX.XXX.XXX.XXX])
Where the X's stand for the IP address you are looking for and an example (not working) of the server. citylocation .State .Prefix. domain. Extension is udr05a.plsntv02.nj.hfc.comcastbusiness.net.
Hope this helps a bit.

Side note:
If the e-mail was spoofed this IP will not be accurate.

Answer 2

Each email address ends with @something.com, all you have to do is type the following at the command line to find the IP address of where the company is located, for example CHARTER.NET:
tracert www.charter.net
This will show you which routers your going through and eventually end with the IP address of the your email server in question.

Answer 3

Yep. Just put on "Full Headers". Its an option in Yahoo mail on the bottom right of any mail you have. One i recently got from dell is X-Originating-IP: [209.11.164.65]
