…when you get a message with the subject line "hey" and the message consists simply of the hyperlinked phrase "Click here to see the attached photos".
That in itself is enough to set off the warning bells. But when the email comes from the account of the former president of a European republic, who I suspect has never said 'hey' to anyone in his life (and who I also suspect might not know how to set up a hyperlink to connect photographs to the message) then I can be pretty certain that it is bogus!
