Huge walls in the form of mountains, gigantic well-guarded gate, strict control over the interior. This is reinforced and represented in the mod with the sudden foulness of Mordor with the sharp cliffs.

Indeed, and as the General has already stated the Eastern Desolation, Ithilien Wasteland, the Brown Lands as well as others already seem to provide an adequate transition between Mordor and neighbouring Biomes.
