Assuming an attic large enough to require a mezuzah (see Yoreh Deah 286:13), is it necessary to put a mezuzah on a horizontal attic door? Does it qualify as a lintel? Should the thickness of the ceiling be considered a doorpost? Shall a blessing be recited?

Kitzur Shulchan Aruch 11:20, citing Noda Biyehudah Tinyana 184, says no: only a standing door requires a mezuzah.
