Not exactly. :P
Like I said, they need belly heat to digest, and so if you give her/him a warm bath, it will basically kick all of the digestive organs into a better gear, and thus encourage the snake to digest further and then poop.
After it's digested this one, you should stick with smaller meals, though, since they are easier for a snake to digest at one time - and if a snake has a meal in their stomach for too long without properly digesting, it will eventually rot inside the snake and cause the snake to regurgitate.
Just so you know, as long as you only feed one or two mice of the appropriate size (in this case we recommend a fuzzy each feeding) then you shouldn't have any problems with getting her/him to poop.
Most corn snakes, when fed right, will poop two or three days after they ate.
