Resolved Spamc not working

[fliegerhermi]

Hi. I just set up a new plesk server for migration from old onyx installation.
It seems that spamassassin isn't working.

I sent an email with the (SpamAssassin Test – netcup Wiki) test-phrase from a google-mail-address.

The score is always 0 and there is not Spam-Header in the e-mail except for the following:
X-Spam-Checker-Version: SpamAssassin 3.4.2 (2018-09-13) on mail.mydomain.de

Mail.log:

Any ideas?
Thanks

Seem you have an ipv6 services active on your server?

Sorry! Very dumm.

IPv6 is not running, but I had a wrong rule update script with sa_update instead of sa-update.
Running sa-update once solved the issue...
