huh.... it's a kind of difficult to tell on here.........('_')
but if anyone know to get the ip adress from email (machine) please tell me

Answer 1

It depends on your context, as e-mail goes through a LOT of servers before getting to your PC. Do you mean your mail server, or do you mean the PC where it originated from (i.e. the sender)?

EDIT FOR ADDITIONAL INFO

If the other party is sending you threats of bodily harm, get the police involved ASAP. Else, forward the harassing e-mail to their ISP's abuse department and let them deal with it.

EDIT FOR MORE ADDITIONAL INFO

If you want to track the sender, it MAY be possible to parse the header of the e-mail, but it's not as simple as it sounds. Usually we track the origin of spammers. Samspade.org has links to a couple tutorials on this subject, but it's pretty advanced stuff, involving SMTP protocol, mail relay, DNS and rDNS lookup, and so on and so forth. Go through their examples and see if you can make sense of it.

Answer 2

REVISION:
First let me say that I am not sure you will get anything. Most spam is sent from a dynamic address that changes periodically.


EDIT:
Actually I just realized I forgot to say something. If the email was sent through a web service like yahoo and not smtp then it is harder to trace.

EDIT 2:
Ah, lies are different. In the USA can be charged under Defamation of Character (That may be the wrong name) however it tends to be hard to prove. One must prove they have had a loss and it is in the civil portion not criminal. Since it is not US so I dont know about the laws their. You will need to go to an expert to take legal action or depending on the Terms of Service they are supposed to abide to can also get their account suspended from the provider. (EX: Yahoo's ToS agreement I belive is an example of one that will shut down their account.)

Feel free to contact me for some help (Getting the header, extracting important info that tells you whether it is legit, etc.).

Answer 3

It's usually in the header of the email. But, remember that you may not be necessarily looking for the IP address but the machine address.

Answer 4

open the email message and look in message headers this will show you IP to lead you back to the ISP, to go further you need a court order
