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!
