I'm 6'3" too and I have about that much sticking up on my 19" bike. As long as it is comfortable it should be ok- they just look a little funny

Actually the seatpost isn't that high, if it was a conventional frame with a near horizontal top tube, you would have about 4-5 inches sticking out, which is the fist full of seatpost setting of old. The only key is, you need to make sure that you have lots of post still inside the frame, take some chalk or a piece of tape and mark the bottom of the post, now pull the post out, most posts have a minimum insertion setting marked on the post, if not, you want a good 5-6 inches inside the frame this will prevent you from over stressing the seat tube. If your post needs to be out past the minimum insertion mark, or you can't get that 5-6 inches, then see if the dealer will swap the post you have for a longer one (they do make really long ones). The other issue is are the bars high enough, sometimes when you need a lot of post exposed, then your bars are too low. The bars on that bike should be higher then the saddle. BTW you may want to trade that suspension post for a solid one anyway, suspension posts suck up a lot of pedaling energy, just make sure the new one is long enough that the minimum insertion mark is below where you need it set.

Just make sure the warning on the seat post is not showing, otherwise you are good.

Are you worried about the seat post, or your riding position? You want the seat high enough that your leg isn't quite straight at the bottom of the pedal stroke. As a starting point, you should be able to straighten your leg by putting your heel on the pedal. Then adjust a tiny bit up or down to suit you.
