I have four servers running Debian 6, with ISPConfig3 in multiserver environment. Should be safe to follow this tutorial to implement only pflogsumm? do I have to take care of something before install and set it? some things are different, but I think it could work. http://www.howtoforge.com/postfix-monitoring-with-mailgraph-and-pflogsumm-on-debian-lenny Please if you can give me some advises it will be great... Looking into files, I have week mail.log rotate set in /etc/logrotate.d/rsyslog, if I add daily log rotate in /etc/logrotate.conf, it will create conflict? do I have to remove weekly cron for mail log in /etc/logrotate.d/rsyslog? Thanks again for any advance. Regards
