Recently I upgraded to postfix-2.7.1. Something changed in the pflogsumm reporting system because now each day's report appears to accumulate for the entire week before resetting. It used to report for only the previous day's maillog, which is why the local file, /etc/cron.daily/1pflogsumm, runs before logrotate does.
I've looked unsuccessfully for the change but have not seen it. /etc/cron.daily/1pflogsumm remains the same as before the upgrade. This file does not specify '-yesterday', but it never has. Please suggest where I should look for the reporting period specification so I can change it from weekly to daily. Rich
