Hm… there could be problem: **the counter isn't reset** when the function is called again. It's reset only when the limit is reached. Or do I miss another case where the counter is reset?

The easiest way could be to introduce a helper function which is called from the main function that breaks the message and to which the recursion counter is passed as a parameter.
