I have received a mail from [email protected].

Is there any way I can check if this domain is owned by Yahoo, or by a scammer?

nslookup returns different results for yahoo.com and yahoo-inc.com.

WHOIS records for yahoo-inc.com don't seem to exist.

  • Yes, sorry to lead you to believe that "Answers" was my only source. I have gotten emails from [email protected] regarding my account, and they have been legitimate.

According to Yahoo's security page (emphasis mine):

  1. Unofficial "From" address: Look out for a sender's email address that is similar to, but not the same as, a company's official email address. Fraudsters often sign up for free email accounts with company names in them (such as "[email protected]"). These email addresses are meant to fool you. Official email from Yahoo! always comes from an "@yahoo-inc.com" email address.

Note: Fraudsters can forge the "From" address to look like a legitimate corporate address (like "@yahoo-inc.com"). Because of this, the "From" address is just one factor to consider when deciding if an email is trustworthy.

I have personally received emails from [email protected] when it was necessary for them to contact me about my account. As the above note says, though, someone could still spoof this address like any other, so keep an eye out. You can probably contact Yahoo's corporate office, via this form to verify that an email is legit.


To check to whom a domain name is registered to you can always use the WHOIS service.

Most website on which you can register a domain name will offer a WHOIS search. For example you can check godaddy whois result and see that the domain is registered to Yahoo.

There are lots lots of other WHOIS search providers that do find yahoo-inc.com::


http://domains.whois.com/domain.php?action=whois -- You need to enter yahoo-inc.com manually

and more......

  • @jonsca - Yes he did but i did the same search and provided results that do find yahoo-inc.com
