I am using ISPConfig 22.214.171.124 on Debian Wheezy and the standard built in spam filtering seems to work fine for most users. However I have a few users where it seems not to function at all. No spam ever gets put in their junk box as specified in the control panel settings. Where would I check manually to ensure the spam filtering is turned on either by user or as a whole? In the database or a config file. Also, if I want to just reset the whole spam filtering set up back to original settings, remove the service and all of its config files then reinstall, what steps should I take? Thanks in advance for any help or suggestions.
