How to enable antispam [Solved]

I just installed the new version 2.10 of antispam with Outlook Express.
All messages are passing thru as if it were disabled. And it is enabled…
How to proceed to solve that issue ?

It’s me again. I unsinstalled and reinstalled CAS 2.1. It works perfectly. It seems that uninstallation of the previous version was uncomplete. :Beer
