@joshuaoxj It essentially checks several combinations of your first / last name @domain.com. Some mail servers are configured so you can't really check, or have a catch-all address, so we can't verify them.
If you tried it earlier, maybe try it again. We had to add a few servers because they get blacklisted for some time after a lot of people use the service.

@domain@giordanobd Thanks for sharing. Not sure why it didn't work for my own domain but I did try and find Ryan and Dick Costolo's email and it worked. Haha.
Very impressive! I ran 5 tests and had a 40% success rate. For the ones that "failed", one explained that there was a catch-all on that domain, the other was a fake test (I searched for a contributor to a news site who doesn't have an email address at that domain) and I'm not sure why the 3rd one failed.
Obviously I get the value, and it's a useful tool to find emails of people you don't know. But it's my belief it's this exact type of tool that will eventually make email fail, and let some new system take its place as a communication client. If anyone can find my email address instantly, then the crap will eventually overrun relevant because it'll get abused by people and systems that are doing it for the wrong reasons.

Is there any way to verify that the email returned corresponds to the person being asked for? For example, I think if I search for "John NotAValidLastName" at somecompany.com, then I'm likely to get john@somecompany.com as a result even though there's definitely no person with the searched for name at the company (and john@somecompany.com is some other John..)
@somecompany@lpolovets No, not really. You can check whether the email is associated to a facebook / twitter account by clicking the icons next to the email address. But thats about it..
