Is the reserve tank running low as well? If yes, you do not have any gasket problem, just a leaking one.
If the leak is between the cap and radiator neck, it is a sealig problem and since you have replaced the cap, the fault should lie with the radiator neck. The top rim of the neck and inner rim of should be flat with no indents.
You mentioned a small recession, if it is a ring on top of the base and the recession is on it, the neck is bad.
Whatever theories that that you have heard, the answer is " NO coolant should be leaking at radiator cap under any circumstances "
