To my knowledge the only item ingame that grants immunity is [Light of Elune] from an Alliance quest in Ashenvale. Just wondering if there are any others. - Idocreating

Not sure if people are aware of this, but the Mage spell Blink creates an effect which gives immunity to everything for a very short time (>1 second), when it is cast, but doesn't remove DoTs. This is what prevents damage when you cast it just before you hit the ground and you take no damage.
