The plastic sleeves protect the post from soil microbes that are the ones responsible for rotting/decomposing the wooden post. So if you are putting the wooden post in soil they will slow the post decomposition process.
Water is not the problem the little air breathing soil microbes near the soil surface are the post killers.
