A bash script to delete old emails. Works with Postfix.
Postfix saves emails in the directory /home/$useraccount/Maildir/new (or cur), but additional folders are created when using IMAP. Additionally, Webmin/Usermin generates extra folders for each email account created under the main account, complicating the deletion of older emails. This script will search for all these folders and remove emails that are older than a specified number of days.
By default it will find and delete emails older than 30 days. If you want to modify the period, replace +30 with +90 in the script.
Just place it in /root/, make it executable, and run it via cron every midnight:
0 0 * * * /root/delete-older-emails.sh > /root/deleted-emails.log 2>&1
or, without logging:
0 0 * * * /root/delete-older-emails.sh > /dev/null 2>&1
The script uses a predefined list of folders. If you want it to run for all folders under '/home', replace the 'paths' array with the code below:
paths=()
for dir in /home/*/; do
if [ -d "$dir" ]; then
paths+=("$dir")
fi
done
