Some one in my office is sending me mails thru his Yahoo account to my gmail account, I just need to trace him/her up since I couldn't figure out who is he or she. I thought I will figure out by knowing his/her IP address but I don't know how to do it, can someone help me ?

The e-mail are being send through servers. There are programs that can trace back the e-mail sender, meaning that they can find the computers ip adress. There are more advanced programs that can even say the exact location (but cost a lot).\nBut this can't be done in general, because not all the e-mails come from a certain ip adress (i'm refering to those computers which connect to the internet by receiving a different ip automatically, though it's the same computer).

No way to know unless he tells you. You could check on the one you know of and see his sent mail, maybe he forwarded or sent something to his other names. Good luck.

If its by email, you can turn on a function in your email to see the source IP of the sender.  This IP will at the least tell what ISP he is using.  Keep all the emails and call your local police department's cybercrimes division.  If your municipal department does not have one, contact your county or state police departments.\n\nMore directly if it is possible, yes.  Our IT department does it all the time.  One example of a program is called PCanywhere.  I do believe it has to be installed on both machines and the IP address of the pc you are trying to control must be known.

Before you start sending out nasty e-mails, the information is still in the e-mail headers and you can't remove them. So while you can send an "anonymous" e-mail, someone can track it down to the computer and computer logs can show when you were logged in and you'll be in trouble.\n\nAs to the actual method to send an e-mail message:\n\ntelnet [server] 25\nyou:HELO [server]\nsvr:250 Hello [server]\nyou:mail from: [your e-mail address]\nsvr:250 ok\nyou:rcpt to: [who you're sending the message to]\nsvr:250 ok\nyou:data\nsvr:354 End data with [CR][LF].[CR][LF]\nyou:[type in your message]\nyou:.\nsvr:250 ok. Queued as [number]\nyou:quit\n\nThis is a standard session and you can locate it in the RFC or most internet sites since it's also part of sysadmin troubleshooting. (I'm expecting this to be flagged as abusive.)

If you are using a yahoo client there is no way you can get confirmed whether the recepient read your mail or not.\n\nBut in case if you use any other mail service apart from gmail or yahoo you might have the request receipt option. On activating this option you will get a receipt whenever the person open your mail and reads .  But unfortuantely many mail services at present do not support this feature

Anyone can get an email address from anywhere. I use one that is based out of Israel, but I live in the US.\n\nInstead, try looking at the header information and look for the IP address. That will tell you more about where she lives than the email address.

IP address tells you where the user logged on from. But to find out his email id from the IP address alone is difficult for us.\n\nIf you are a government agent, you can determine the ISP from the IP address range and then use the ISP's log file to get the data on what sites / mail servers the user was connected to.

Despite what other people said you can trace an ip address.  First run the ip through an ip address tracing program on the internet.  Just google ip address trace or something and you will get alot of results.  Use one to find out where the addresses is ie. California, Montanta, New York.  Then get the ISP.  Once you get the ISP go to the ISP's website.  Go to contact us or something similar.  Find where it says Abuse.  Send an e-mail with the ip address you want to trace and tell them why.  If you have a good enough reason they will give you the phone number of the computer that connected to the internet through them.  Then with the phone number it is easy enough to get the name and address.

You can always try looking up the e-mail adress in a web search engine. In older public forums the address was shown in clear text.\n\nQuite often the domain (the stuff behind the @ sign) can give hints about the sender, or the user handle before. Yahoo addresses may have a public profile which sometimes give you hints or information.\n\nIn the age of spam, more often than not the sender address is faked, though. In that case you couldn't even reply.\n\nAlternatively, you can use a second, free e-mail account to reply to the sender without revealing your identity. But then the original sender will be in the same situation you are in now...

if you want to send an incoming mail to others.. use the redirect option from your mail acccount.. the only thing is that the reciever wont get your e mail account but rather the e mail id of the person who has sent you the mail;..\n\nregards\nparvesh garg

Look at the full headers of the email.  Look for the X-Originating-IP.  Search that IP # on http://www.arin.net/whois/  It will show you info on their internet service provider and you should be able to narrow down where the person lives based on that info.

No.  Email addresses are independent of IP.\n\nHowever, you can probably get the IP address of the default mail server for the account.  Open a command window (Start>run>'cmd') and type "ping mail.(domain).com" where (domain) is the domain from the email address.  If that doesn't work, try "ping smtp.(domain).com".

go to profiles.yahoo.com/yahoo_id\n\nreplace yahoo_id with the yahoo id of the person

Check the FULL headers in your "friend's" email. They will show his/her IP address. You can then trace their location using http://www.hostip.info/. I hope this helps
