Yea it was clearly marked SECRET/NOFORN, and looks like it was declassified 1 Apr 2012. Was this email on the server before it was declassified? The daily mail tried to make the story essentially Bush lied and people died. But, the other part of the story is Hillary lied, about never having received or sent email that was marked classified.
Under EO-12958, “DECL: 04/01/12” meant that it would be reviewed for declassification on that date.
Also note at the bottom of the page that it was ‘declassified’ with redaction’s on Jan 23, 2014, in response to a FOIA request.
