Can the IP an email is sent from be faked?

Yes you can use an anonymizer. This allows you to surf anonimously and send email to people even proportedly from their own IP.\nhttp://www.answers.com/anonymizer?gwp=12&method=2

Assuming they don't give themselves away by telling someone they did it? Nigh impossible. You would have to find out what ip it was sent from, then hack the isp to find out who was using that ip. Not an easy task for even an expert hacker, and highly illegal. And that would only tell you who pays for the internet service. If they sent it from say, a library, you would then have to somehow find out exactly who was sitting at that pc at that exact time. Basically it would take more time, effort, and skill than anyone is willing to put into it, just to find someone calling them names.

Here is a link for interpretting email headers. If you have any of the bogus email you can get alot of the info you need (IP address etc) from the header. TX\n\nhttp://www.stopspam.org/email/headers.html

The only part of the headers that you CANNOT forge is the Received: lines.\n\nTherefore, use it to detect if its spoofed\nHow? go here\nhttp://www.dnsreport.com/\n\nTo use the Mail Test tool, just enter a domain name ("example.com") or an E-mail address ("user@example.com"). If you enter a domain, the Mail Test tool will show which server(s) are used for mail delivery for the domain, and what order they should be used in. If you enter an E-mail address, the Mail Test tool will also try connecting to those servers.\n\nAfter getting results, compare and analyze\nExperience and you'll the difference

yes. IF you have yahoo mail, go to Options on the Top right >> Mail>>General Preferences then at Messages Headers: select the "Show all headers on incoming messages"\nThis will show the originating ip addresses. There are websites where you can reverse lookup ip addresses. do google search for ip address reverse lookup.

The email would have to be encrypted if sent normally, but would be okay if the files came over a VPN tunnel connection

You can show headers.\n\nBut if it is a Yahoo email, it will return with Yahoo IP address, which won't tell you anything you don't already know.

So you cannot see the specific IP address of the sender, but you can trace back to their email gateway.\n\nThese instructions will vary depending on the email client you have, however, it should be possible to view the internet header. For example on Outlook, you can do this within the message by, selecting view, then options.\n\nAnyway parse through the header and you will see the IP address of the various servers the message has passed through.

there is a field named "Received" in the full header of you email, containing data like this:\nfrom [168.243.7.66] by web25610.mail.ukl.yahoo.com via HTTP; Thu, 22 Jun 2006 00:13:58 CEST\nYou can see an IP there. You can know what country that IP belongs to.\nhttp://www.dnsstuff.com/

well, I think you can't do that just by sending an email, you must know the ip address itself, to know that ip you must receive a response, reply from the person  you sent the e-mail to and your e-mail reader must be set-up to show full headers. The header of an e-mail shows the ip address from the incoming message, once you have that ip, go to http://www.ip2location.com/ to trace it, or https://www.abika.com/forms/Verifyemailaddress.asp

erm you need more details but you can create a fake e-mail address ,but that takes a lot of steps and includes telnet. Telnet can put your computer in danger if another hacker finds it. Also if you have telnet you have to get permission from your ISP(internet service provider). If you want to encrypt the things in the e-mail I suggest you use a PGP. PGP is a program that encrypts your data. The only thing that can break it is by brute force.\nhope I helped...\nBTW even if you used some services that will protect your e-mail account from being recognized the can still send a probe that will find out what your true e-mail adress is.

Quite often, send addresses are faked, so you must make sure it actually came from a Yahoo account. If you're using Yahoo yourself, or a few other services like GMail, the sender should have been verified by DomainKeys. \n\nIf you're with an ISP that doesn't support DomainKeys, you'll have to view the full headers of the message in order to check it really did come from Yahoo. There is a service, SpamCop which will do this for you.\n\n"If the spam or abusive e-mail is being sent from a Yahoo! UK & Ireland account (eg: johnsmith@yahoo.co.uk) please forward the entire message with full headers to uk-mail-abuse@yahoo-inc.com. If it originates from a Yahoo! US mail account please forward it to abuse@yahoo.com. This will assist in a prompt reaction to your report."

This is a common thing that spammers do, it's called forging the header.  Spamcop.net can trace down to the ISP that was used to send the e-mail.

If it's a Yahoo account, just email it to spoof@yahoo.com.

In case of yahoo open the email, scroll down to the bottom right, click on full header, the IP written beside "received from [x.x.x.x]" is the ip of the originating pc...the full header option is available with most of the email services...after that you can use ip lookup services to find out which ISP the ip belongs to...however if the sender is using dsl or some sort of nat/internet connection sharing (i.e; private ip) then it is difficult...to the trace the exact pc...X-OriginatingIP is the ip of the mail server. Even if the ip is dynamic the ISP can tell which pc has been alloted that ip at that particular time.
