Perhaps have a look at my post "Flying though space" in 
povray.binaries.images.

Though the effect was made with particles in space in mind, it should work 
well for rain drops too. What is does is to create particles only in the 
area around the camera. This would probably work well to create all the 
visible rain drops. You can then combine it with media as the others here 
have mentioned (or other tricks) to also simulate the overall rainy 
atmosphere at long distance.

By the way - note that Gilles Tran's famous rainy city image "The Wet Bird" 
was made without having any rain drops in the scene at all - it's all made 
with wet looking textures combined with the right atmosphere.
