I would try reunion.com. Even if you don't find who you are looking for, if they join then they will be notified that you were looking for them! Then you get connected ( an e-mail that they were found, etc.).

Most likely, you can't.  Running a trace on the email will only lead back as far as the ISP.  Only thing I can think of is that you can try an internet search on the email address, and see if you get any hits, or do an internet search for "reverse email lookup" and try one of those sites.

If the person didn't leave a forwarder on their old address, you can try and track them down using a search engine.  There are several sites that list peoples names and e-mails as well.

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

I don't know what they used to have, but Yahoo! Messenger doesn't have this feature now, for user privacy. If it's really your friend, though, you can always just send an IM asking which room he's in.

You can check directories, like http://www.infospace.com. Generally, though, there's no sure way to link a person's identity to their e-mail address.

Even though technology has advanced far enough to have people access various entertainment and aid applications, there is no legal way to know if a person recieved their Yahoo! mail, atleast none that I know of. True, they may send you a reply if it is appropriate, or they will notify you personally, but none have been devised to do so.

You go to Yahoo People Search and type there name and it should give you there yahoo id if they are listed some are not listed you have to choose to be listed in the directory.
