Spamassasin is set to 5 and it only score 1.8 so it won’t do anything.
SPF shall reject or flag the email but I have not been able to set it up for that.
In these cases I prefer to block those emails with postfix black lists (specially when the spam email is higher than 500 emails per week). As a matter of fact IP unknown [11.22.33.44] is blacklisted and shall be rejected right away. I combine black list with fail2ban rejection in order to not deal with those pesky ips very often. There is a long discussion about using or not using the black lists
