Back in Oct'08 David Stiller posted a nice script for cleaning up
graylist trees. Unfortunately, it doesn't work as well as it might with
v4.0 graylist trees, leaving empty directories behind.
I've taken the liberty to use it as a base for a new script I've written
for v4 (and v3) spamdyke graylists. The attached qtp-prune-graylist
script is part of the qmailtoaster-plus package
(http://qtp.qmailtoaster.com). The script can be obtained there on its
own without having to install the whole QTP package by browsing the svn
repository, and selecting "Original format" at the bottom of the page.
It can be run stand alone, and requires only a spamdyke configuration
file to operate.
The script obtains the graylist location and duration parameters from
the /etc/spamdyke/spamdyke.conf file by default. If you have a spamdyke
configuration file in another location, simply edit the script to point
to that location. If you specify these configuration parameters in
spamdyke's command line, you'll need to modify the script appropriately.
The script handles any number of domains and accounts. A recent run on a
host that had been running spamdyke v3.x for quite a while produced:
qtp-prune-graylist total - 17 domains processed
qtp-prune-graylist total - 1134404 entries found
qtp-prune-graylist total - 1128058 entries removed
qtp-prune-graylist total - 0 empty directories removed
qtp-prune-graylist total - 6740 graylisting entries remain
This host had run out of inodes before the script was run. Afterwards
12% of inodes were in use.
Counts by domain are shown as the script runs. There is an -s flag
available for silent running (think cron).
You'll probably notice that after running the script, the --config-test
option of spamdyke runs a bit faster, as it walks the entire graylist tree.
There is no option for trial run like in the former script. That seemed
like a waste to me.
Please use the ticket system provided at http://qtp.qmailtoaster.com to
report any bugs or make any enhancement requests you might have.
