Problem description
The postfix server receives many brute force login attempts, port scanning and other attacks. No actions are currently being taken against these connection attempts.
Solution description
The postfix server should be secured by using something like fail2ban to reduce generic attacks and resources for many unwanted connections. This feature should be enabled by default and can be disabled with an environment flag.
