INN (InterNetNews), originally written by Rich Salz, is a very full-featured and extremely flexible and configurable Usenet / Netnews news server. For a complete description of the protocols behind Usenet and Netnews, see RFC 3977 (NNTP), RFC 4642 updated by RFC 8143 (TLS/NNTP), RFC 4643 (NNTP authentication), RFC 4644 (streaming NNTP feeds), RFC 5536 (USEFOR), RFC 5537 (USEPRO), RFC 6048 (NNTP LIST additions), RFC 8054 (NNTP compression) and RFC 8315 (Cancel-Lock) or their replacements.

In brief, Netnews is a set of protocols for exchanging messages between a decentralized network of news servers. News articles are organized into newsgroups, which are themselves organized into hierarchies. Each individual news server stores locally all articles it has received for a given newsgroup, making access to stored articles extremely fast. Netnews does not require any central server; instead, each news server passes along articles it receives to all of the news servers it peers with, those servers pass the articles along to their peers, and so on, resulting in "flood fill" propagation of news articles.

A news server performs three basic functions: it accepts articles from other servers and stores them on disk, sends articles it has received out to other servers, and offers stored news articles to readers on demand. It additionally has to perform some periodic maintenance tasks, such as deleting older articles to make room for new ones.

Cool, oldschool and written in C.

@robi No Docker for it, mature software but still receiving development.
