Hello people, I recently purchased SpamAssassin as an add-on to our existing Plesk solution. I got an updated license key and the SpamAssassin button became available on the Plesk server control panel. So far so good. I select the SpamAssassin button from the Plesk server control panel and select both "server-wide settings" and "personal settings" options. However, when I now go to individual mailboxes, I cannot activate SpamAssassin. When I hover over the button in the mailbox setup control panel, the help page to the left tells me "Spam filtering is currently unavailable. To enable spam filtering you need to have the SpamAssassin software installed, and the support for user-level spam filtering enabled on the mail box management page." Now, I never installed the SpamAssassin software itself, but I suppose it has been installed during the initial Plesk setup. When I look at the services in the service management, I can see the service is running and I can stop and restart it. Am I wrong and need I to install extra stuff here (and is that documented somewhere), or could there be something else ? Regards, Benoit.
