I am getting constant spam from different email addresses but with similar template.
So, what I did:
So, I added
body_checks = pcre:/etc/postfix/body_checks
/etc/postfix/main.cf with the content:
/My malware uses the driver/ REJECT
sudo postmap /etc/postfix/body_checks sudo systemctl restart postfix
However, I’m still receiving spam of that same template, what am I doing wrong?
