eximstats-cron

eximstats-cron is a cronjob that runs eximstats on your machine.

eximstats is installed with exim4-base on Debian/Ubuntu, so ut probably already exists on your system. Why not use it to generate mailstatistics? :)

eximstats-cron will use eximstats to generate daily, weekly, monthly and yearly statistics in HTML form which you can easily serve using some webserver.

Logging in exim4

For this script to work, you need to generate daily exim-logs. The following option will make Exim output logs to /var/log/exim4/mainlog-YYYYMMDD. log_file_path = syslog : /var/log/exim4/%slog-%D It needs to go into your exim4-config.

Since I like to find my latest logfiles in a location that doesn’t change every day, I have the following two lines in cron to make sure there is always a symlink pointing to the latest logfile. ```

This just symlinks latest logfiles

The backslashes before % in date escapes %, because they’re a special cron-character.

00 00 * * * Debian-exim rm -f /var/log/exim4/mainlog-latest && ln -s /var/log/exim4/mainlog-$(date +\%Y\%m\%d) /var/log/exim4/mainlog-latest && touch /var/log/exim4/mainlog-$(date +\%Y\%m\%d) && chmod 640 /var/log/exim4/mainlog-$(date +\%Y\%m\%d) 00 00 * * * Debian-exim rm -f /var/log/exim4/rejectlog-latest && ln -s /var/log/exim4/rejectlog-$(date +\%Y\%m\%d) /var/log/exim4/rejectlog-latest && touch /var/log/exim4/rejectlog-$(date +\%Y\%m\%d) && chmod 640 /var/log/exim4/rejectlog-$(date +\%Y\%m\%d) ```

Setting up eximstats-cron

Just clone this repo somewhere, and symlink eximstats-cron into /etc/cron.daily/. Easy-peasy. The logs will start to appear in /var/log/eximstats the very next day!
