The var/spool/filter directory of our installation is currently taking up 20GB of disk space. Is it safe to purge these files, or is there a way to configure the system to purge them?
This seems to be related to Bounce Management, which is why I'm asking in this forum.
You can safely delete the files in this directory. The files contain copies of all feedback mails filtered by the OpenEMM mailloop (probably primarily spam replies).
