Missing Cron Email When Restarting smtpd

I have a cron job that renews an SSL certificate from Let's Encrypt, and then restarts the smtpd daemon so that the new certificate is picked up. This all works fine--as proven by both the presence of a new, valid cert on disk, and smtpd successfully restarting--but cron never sends an email with the output of the job. What gives?

cron(8) now supports random ranges with steps.

Thanks to the following commit by Todd Miller, cron now supports random values in a range with a step value (i.e. "<lo>~<hi>/<step>" in crontab entries)...
