Purpose
This script deletes messages in all folders for all users that are older than a specified number of days except for those messages that are either unread and/or flagged.
Usage
The script accepts 2 parameters with 1 being mandatory. The basic usage is as follows:
./mail_prune.sh -d|--days x [-p|--path|--mailcow-path path]
In the above:
| variable | meaning |
|---|---|
| -d --days |
Delete messages older than this many days |
| path | The path to your mailcow-dockerized installation directory. By default, this is /opt/mailcow-dockerized |
Please note:
- When specifying the number of days, you can use any of the switches -d or --days
- When specifying the path to your mailcow-dockerized installation, you can use any of the switches -p, --path or --mailcow-path
Examples
Delete messages that are read and unflagged for all users in all folders that are older than 366 days:
./mail_prune.sh --days 366
Same as above, but mailcow-dockerized is located in a non-default location, say /var/mailcow:
./mail_prune.sh --days 366 --path /var/mailcow
Script notes
Most important: Regardless of age, this script will not remove any message that is either unread or flagged.
Because this script is meant to run via CRON, there is not much in the way of error-trapping or user feedback. Specifically, any failures in the doveadm command will not be logged to the console or otherwise stop the script from executing. You would have to check the docker container logs for details on any errors. The script only checks that all parameters have values and that it is possible to change to your specified mailcow-dockerized directory -- not that it is necessarily the correct directory.
Because of this lack of error-checking, you may want to run this script manually and check the results in the docker container logs before running it as a cron job.
