Where is monster spawn disabled?

[NateN]

I know its disabled on pressure plates, but is it disabled anywhere like at a certain height, area, etc?

Where are all the places and conditions in which monsters will spawn?

Well, those are by default. I'm talking about server-specific disables that optical put in. Like spawning on pressure plates.
