Posting is simply rising to the trot with the one-two, up/down rhythm of the horse. Try telling your horse you want to be against the rail before you get to the bend in the arena. Also, keep your leg on the horse. If you're sending him forward it will make it easier to guide him. So, as you approach the turns send him on with your legs, and guide him through the turns using the aids you've learned. If the horse is very responsive all you will need is increased inside leg pressure on the girth and a little (and I mean little) squeeze of the inside rein, while sending the horse on. Oh, don't forget to maintain contact with both reins the entire time you're riding, including through the turns. When I first started riding I always allowed my outside rein to drop, and the horses always took advantage of this by cutting the corners or taking control of the ride and heading for their friends or my instructor.
GOOD LUCK!
