This Is For Real

I received an e-mail from someone I don't know that wants to give me a large sum of money.  He says this is for real:

CONFIDENTIAL
I am a straight forward person and this is the same way I Would like for
you to respond to this email, should you be interested in it's content or
not.

I know that this message will come to you as surprise as we do not know
each other. I am MR. HAHN YAO, an accountant of Export and Industry bank.
(Philippines) There is an account opened in this bank in 1999 with a huge
sum and since 2001 nobody has operated on this account again.
Investigations revealed the owner is dead without a beneficiary. I am
contacting you so the funds can be transferred to your name as a
foreigner.. Contact me via my email: hahnyao@somename.com so I can give you
the details.

I look forward to your reply
N/b i do not need your help with legal bills so you do not have to worry
about sending me money. this is for real.
MR. HAHN YAO

Now, I'm not saying that I don't believe Mr. Yao, I'm just not sure why he sent this to undisclosed recipients instead of just me.  And I wish he'd just mail me the money in cash rather than e-mailing me and asking me if I would be in any way interested in legitimate free money.

"This is for real," he says.

What is real?  How do you know what you believe is really real?  :)  That's a real hard question.  Really.
