spamassassin plugin stopped working

anyone knows how to fix spammassassin plugin?

I tried to restart all the services but it did not work anymore ....

Danke, habe das Plugin incl. Spamassassin deinstalliert und neu installiert ... läuft wieder
aber seltsam ist es ja, lief seit 3 Wochen ohne Macken
spamass.sock war vorhanden

Thanks. I've uninstalled and re-installed the plugin and all is working again...
This is really strange because the plugin has been running well for the last 3 weeks without any problem.
The spamass.sock was there.
