I'm fine tuning my install of ispconfig. I noticed an issue with spam rule update of spamassassin: By default updates are not enabled in debian, which might be an issue. To enable them change CRON=1 in /etc/default/spamassassin. I'm not sure if this is an ispconfig issue or if it's mentioned somewhere in the documentation.
ISPConfig does not alter the debian defaults in /etc/default/spamassassin. But we should add a note in the install guides to activate it.
It's up to you to mention it. It should be a "good admin" duty to check these things and not assume they work out of the box. One of the things I like about ispconfig is that it does not hacks the standard system too-heavily, which means it's easy to customize it to do what you need it to do. Just in case, here's what needs to be done on the standard debian install: Enable spamassassin updates in /etc/default/spamsassassin CRON=1 Call the cron job once by hand to create the update dir and to update it #/etc/cron.daily/spamassassin Link spamassassin update dir to the one than spamassassin run by amavis uses: #ln -s /var/lib/spamassassin/3.003002 /var/lib/amavis/.spamassassin/
