I just noticed that the mailman bounce log messages aren't going into /var/log/mailman/bounce, but rather to /var/log/mailman/bounce.1. It looks a lot like logrotate did the actual log file rotation, but didn't do whatever it takes to make mailman close its log files and open them again. -- "To announce that there must be no criticism of the president, or that we are to stand by the president, right or wrong, is not only unpatriotic and servile, but is morally treasonable to the American public." -- Teddy Roosevelt
