To answer your questions. I have not tried the techniques of postfix alias and periodic.conf that you have been so good as to point out. Lets step back and look at the big cron picture. Cron is designed as per the cron manual pages to use rc.conf cron_flags= option to over ride the default "root" destination. Now you state and tests prove that the cron periodic routines reroutes its output independent of cron's settings. To my way of thinking this is the definition of the bug I am experiencing. The periodic routines are in error by not adhering to the cron design standard. The periodic routines need code added to them to comply with the cron design and check for or use the value in the flags option to over ride the destination. Adding the statements you previous posted to periodic.conf is a work-a-round, not a fix or the correct method as per man cron. The goal here is not to just get things working by a secondary method, but more to the point of getting bugs corrected. Thank you for pointing out the cause of this bug. I am going to post a bug report on this.
