@pitrh when do you remove an entry from the blocklist? If an entry was due to a server being hacked, and it has been freshly assigned to a new customer inheriting the IP, how should that person proceed to not be blocked?
Also, a note about logs, due to GDPR it may not be legal to keep emails logs more than 2 or 3 years 😅 , but I'm not an expert and different laws of countries or EU often collide. It's still something to think about though.
