I see scammers have found a new way to get around email spam filters. They put the scam info ("I have 10 million dollars" etc) into a picture format and attach the picture to the email they send you, then just put this into the email body itself:
"You have been contacted in confidence, kindly go through the attached proposal and respond urgently thank you, on the alternative I can be reach through Tel: +44793745XXXX. Mr. Richard" (I just removed the last four digits of the actual phone number in the email)
+44 is for British international dialing, but the actual scam is talking about US dollars.
