No more BAYES hits after upgrades

Hello,

I recently upgraded my central Amavis server from CentOS 7 to Rocky 
Linux 9, which brought a few version changes in the relevant packages:

  * amavis 2.12.3 -> 2.13.1
  * spamassassin 3.4.0 -> 3.4.6
  * rpsamd 3.8.4 -> 3.13.2
  * dspam is no longer available on Rocky Linux (was 3.10.2 on CentOS 7)
  * clamav 0.103.11 -> 1.4.3


Things mostly work, but I noticed that the new server never lists 
'BAYES' in the tests list.

tests=[DKIM_SIGNED=0.1, DKIM_VALID=-0.1, HEADER_FROM_DIFFERENT_DOMAINS=0.001, HTML_MESSAGE=0.001, HTML_MIME_NO_HTML_TAG=0.635, MIME_HTML_ONLY=0.1, RCVD_IN_MSPIKE_H2=0.001, RCVD_IN_VALIDITY_RPBL_BLOCKED=0.001, RCVD_IN_VALIDITY_SAFE_BLOCKED=0.001, SPF_HELO_PASS=-0.001, SPF_PASS=-0.001, R_UNDISC_RCPT=3, R_DKIM_REJECT=0, DKIM_TRACE=0, MIME_HTML_ONLY=0.2, ARC_ALLOW=-1, RCVD_TLS_LAST=0, ASN=0, FORGED_RECIPIENTS=2, DMARC_POLICY_SOFTFAIL=0.1, FORGED_SENDER=0.3, DKIM_MIXED=0, RWL_MAILSPIKE_POSSIBLE=0, TO_DN_ALL=0, R_SPF_ALLOW=-0.2, FROM_HAS_DN=0, MIME_TRACE=0, RCVD_COUNT_FIVE=0, MISSING_XM_UA=0, TAGGED_FROM=0, RCPT_COUNT_ONE=0, MID_RHS_NOT_FQDN=0.5, FROM_NEQ_ENVFROM=0, R_DKIM_ALLOW=-0.2]


I only trained the new server for a couple of days now, could it be that 
it just didn't gather enough training data yet?


    Best regards,
