How are the dkim, spf, dmarc settings in spamassasin for incoming mail if the email server does not have a record, it is immediately tagged as spam

The scores for individual failing checks can change with every spamassassin rule-update. AFAIR, since SPF,DKIM, DMARC are all not the greatest indicators for spam or ham, the rules are not usually scoring too high

please provide the logs of such a mail - this should give some hints at what might profit from reconfiguration
 
The SPF record is already been very useful and quite well implemented. Also rDNS.
But almost no one is interested in DKIM/DMARC, which is a shame.
I have now turned off the checks completely, because <1% of servers use them and many of them are also configured incorrectly.
