CONTRIBUTING.md

+# Which code branch to use
+
+The master branch is used for code (mostly new features) that shall go into the next major release (e.g. 3.2, 3.3 and so on). The stable branch (e.g. stable-3.1, stable-3.2) is the branch for the current intermediate and bugfix releases. Bugfixes shall be committed to the current stable branch and not the master branch. The stable branch is merged to the master automatically from time to time, please do not submit bugfixes a second time against the master.

docs/hardening/README.md

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
+
+This folder contains examples for further ISPC hardening (done by NwSEC)
+
+
+Currently, these are:
+
+
+
+anti-bruteforce         WordPress Login Anti-Bruteforce via fail2ban
+
+postfix-ldap            Query for valid recipients via LDAP in a transparent
+                        setup routing mails e.g. to the internal server
+                        
+                        
+                        
+All these examples have been productively tested and implemented on various
+Debian/GNU Linux based systems.

docs/hardening/postfix-ldap/README.md

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
+
+If mails get transparently forwarded to another mailserver, a mechanism to block
+mail for invalid recipients makes sense, and drastically increaes the well-known
+backscatter problem.
+
+LDAP queries are used to check for valid recipients, and forwards the mail, if
+an entry for the user is found.
+
+For this to work, on Debian/GNU Linux, you also have to install postfix-ldap by
+
+apt install postfix-ldap
+
+
