Well, what is there to say about this E-Mail? It's a classic scam mail; writing about a large sum of money, wanting the receiver to reply as soon as they can, and of cause (who could forget?) poor English.
Probably one of the main reasons why "Barrister Frank Kufu" send this message in an image form is so it would not get detected by whatever the anti-spam protocol the users E-Mail host has, in the case of Juno, the spam-filter was likely last updated whenever they last updated their site layout, so 2004...?
By doing a simple search of the opening line ("Dear , I am Barrister Frank Kufu") came up with a few results; first was a result from The Scam Directory, who list an index from the 13th of September 2016 that reads the exact same way.
Last we have a result from a Trello group who lists the same E-Mail.
