There's no way to tell, other than asking them.

Go to Yahoo email people search and put in their real name. If they have a profile with their real name showing it will give their email address

Despite being a simple thing, predicting someone's email address is very very difficult, let alone finding.\n\nYou cannot be sure that Bill Clinton's email id will be bill_clinton@....com.\n\nSo your search is going to be really tough unless you have some clue on this person's user id patterns.\n\n.:Fishie:.

Depending on what email you use there are diff ways to do this.  But basically go to the advanced view for the email.  And you'll get a lot of extra info with the email.  Find the IP address in the 'from' header,  go to www.dnsstuff.com and type in the IP address you found.  You'll get a fair bit of info from this.

You ask them.\n\nThere is not a really good place on the internet to look up e-mail addresses. If they blog you might be able to find it at their blog.

Very low probability to find such way. There are many email directories available like as phone book. But how many of us submit our profile with our email address to those directories?

Their is no site available , where you find new email addresses.\nBut you can try for yahoo search and you find how long the ID made before.

Generally speaking you can not search a person by email address. Email addresses are stored in secured databases which are protected from public access.\nThere is always a chance that someone put the email address along with other contact information as some text in public open forums, blogs or discussion groups and most of the search engines can pick these up. Wrong thing to do:)

Yes and no, the best way to go about this is to click full headers on the email (under yahoo), look at the email address's full ip and than do a whois on the ip.  You won't get a person, per say, but you can see where the email is coming from!
