I've receive a email out of the blue saying my last will of 10mill I would like to give it to you from a random person thry also gave me the ref# and the attorneys email and name said for me to contact them with this specific email is this ascam or what?

Very much a scam. Random email from a person you don't know? Actually a very common scam. I bet they are from Ghanna or someplace similar.

You think you have a long lost relative that had 10 million to leave you? This is almost definitely a scam. Do no give any personal info to anyone related to this.

In fact just replying to the email will get your email sold worldwide to other scammers, because you will be seen as a gullible person.

Just to add - if an attorney was trying to locate a long-lost relative about an inheritance he wouldn't send an email. He would call, or send a letter, and would include information such as what relative has died, date of death, etc. And besides - how would an attorney in this situation even know what your email address is? One final tip off - I bet the email wasn't addressed to you by name, but was addressed to "Dear Sir" or some such generic greeting that shows he doesn't even know your name - right?
