A small search resulted in the following code:

Function IsEmail(Byval email as string) as boolean
    Static emailExpression As New Regex("^[_a-z0-9-]+(.[a-z0-9-]+)@[a-z0-9-]+(.[a-z0-9-]+)*(.[a-z]{2,4})$")

    return emailExpression.IsMatch(email)
End Function

I know how to make sure it's in the correct format but I want to actually see if it exists. But thanks for your help anyway

Oh I'm sorry, I misread. I don't know the solution I'm afraid.
