Hi Odhiambo. Lovely to receive an email from you after all these years!
I've spent some time looking at the rspamd website following your
mention of it. I'll turn to that if I can't improve my spamassassin
performance!
For RDNS do you recommend something along the lines of
drop message = REJECTED - Sender Verify Failed and no RDNS
log_message = REJECTED - Sender Verify Failed and no RDNS
!verify = reverse_host_lookup
!verify = sender/callout=2m,defer_ok
!condition = ${if eq{$sender_verify_failure}{}}

Kind regards
