Here is headers of one email where spam comes through:

ReverseDNS: No reverse DNS for mailserver at 194.5.148.131, +60 Spam score
X-DKIM: signer='vadenttech.in' status='pass' reason=''
DKIMCheck: Server passes DKIM test, -20 Spam score
X-DKIM: signer='[email protected]' status='pass' reason=''
X-Spam-Bar: ++
SpamTally: Final spam score: 47

Note we set in spam scoring to 8 and high spam threshold to 15 in spamassasin setup in directadmin and we use rspamd

However the mail above still came through.

So we also had the following set:

[root@da-1 ~]# cat /etc/exim.easy_spam_fighter/variables.conf.custom
EASY_NO_REVERSE_IP==60
EASY_SPF_FAIL==60
EASY_DKIM_FAIL==60


To solve this if we increase EASY_NO_REVERSE_IP to 100. Would the email have been dropped?
