Hi, this is my first project written in Go. It is a Postfix policy service that can help reject compromised sender accounts. Therefor it takes the sender IP and gets its geo location ISO code. If a sender comes from too many countries, the request is rejected. A second feature is to count the number of different IPs and if a certain amount of addresses were seen, the request gets also rejected.
There is a whitelist option, where settings can be modified for any sender account. Furthermore this little policy service has also LDAP support. It is limited to LDAP with or without StartTLS and with simple bind or SASL/EXTERNAL. PRs are welcome. The suggested way to use this service is by running it as a docker container. A Dockerfile and a sample docker-compose.yml file is included. As said before, this is my first project in that language. If you are a Go pro, feel free to help make it better ;-) Hope you enjoy https://gitlab.roessner-net.de/croessner/geoip-policyd Christian Rößner -- Rößner-Network-Solutions Zertifizierter ITSiBe / CISO Karl-Bröger-Str. 10, 36304 Alsfeld Fax: +49 6631 78823409, Mobil: +49 171 9905345 USt-IdNr.: DE225643613, https://roessner.website PGP fingerprint: 658D 1342 B762 F484 2DDF 1E88 38A5 4346 D727 94E5
