      I think the main issue (you need to decide how much of an issue
it is) is that the informational emails depend on the same cronjob
(for a lack of a better term) that rotates the logs. In my case I did
not care much about that, hoping warning emails will be sent
regardless, and I delegated log rotating to the system (rsyslog +
logrotate in my case).
