Cashunit R.b.i-online.[protected]@hotmail.com — Received mail from cashunit r.b.i-online.[protected]@hotmail.com using the name of RBI

I received a mail from cashunit r.b.i-online.[protected]@hotmail.com sent to my email id advocate.[protected]@gmail.com containing a letter stating to receive an unclaimed amount and submission of personal information. Now if the mail using the name of RBI is fake then my request to the RBI authority to take step against the unknown sender. Hence it is very unfortunate that some one send mail in the name of RBI and RBI has no security policy to prevent this type of mailing system which is spoiling the honest and goodwill of RBI. please response to my complain.
