Based on the underlying mechanisms of the CentOS Linux 7.5 operating system, which in turn is based on Red Had Enterprise Linux 7.5 operating system, NethServer 7.5 is here more than six months after version 7.4 released last October and introduces numerous new features and enhancements. Highlights of the NethServer 7.5 release include a new NethServer Subscription by Nethesis that promises to give users access to both the Stable Updates repository and professional support services they might need for NethServer deployments, as well as an all-new mail server and spam filtering system based on Rspamd.
