Newsbin is a multithreaded news robot that automatically downloads and decodes binary posts to usenet newsgroups. Newsbin will take full advantage of high bandwidth internet connections by allowing multiple simultaneous connections to your news server or servers. It re-assembles multi-part posts across multiple servers and includes real time rendering of thumbnails when downloading images. Newsbin supports regular expression parsing for complex filtering capabilities based on subjects or filenames and provides file size filtering. A spam filter function identifies likely spam posts that are either password protected RAR files or RAR files containing trojan executable files.
