An administrator sets the maximum number of recipients for a single email, a setting whose shipped value of 0 stands for no ceiling at all. A scheduled job then carries a recipient list longer than the value that was set, and the list is broken into shorter lists. Which lines of the message does that ceiling count, and why does the documentation say a ceiling is worth having?
