X-No-Archive
''X-No-Archive'', also known colloquially as xna, is a newsgroup message header field used to prevent a Usenet message from being archived in various servers. Origin The need for X-No-Archive began when DejaNews debuted in 1995. DejaNews was the first large-scale commercial attempt to archive the Usenet news feed, and several newsgroup participants were concerned about privacy rights and about the possibility that their messages could be re-posted through DejaNews in the future. DejaNews addressed these concerns by announcing that it would not archive Usenet messages containing the X-No-Archive header field. How it works X-No-Archive was designed to follow the standard message header protocol, RFC 1036 and RFC 977, used in existing newsgroups. In addition to the standard header fields used in all newsgroup messages (including ''Path:, From:, Subject:,'' and ''Date:''), news reader software allows a user to add optional fields to a header. According to RFC 822, these additiona ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Usenet
Usenet (), a portmanteau of User's Network, is a worldwide distributed discussion system available on computers. It was developed from the general-purpose UUCP, Unix-to-Unix Copy (UUCP) dial-up network architecture. Tom Truscott and Jim Ellis (computing), Jim Ellis conceived the idea in 1979, and it was established in 1980.''From Usenet to CoWebs: interacting with social information spaces'', Christopher Lueg, Danyel Fisher, Springer (2003), , Users read and post messages (called ''articles'' or ''posts'', and collectively termed ''news'') to one or more topic categories, known as Usenet newsgroup, newsgroups. Usenet resembles a bulletin board system (BBS) in many respects and is the precursor to the Internet forums that have become widely used. Discussions are Threaded discussion, threaded, as with web forums and BBSes, though posts are stored on the server sequentially.

DejaNews
Google Groups is a service from Google that provides discussion groups for people sharing common interests. Until February 2024, the Groups service also provided a gateway to Usenet newsgroups, both reading and posting to them, via a shared user interface. In addition to accessing Google Groups, registered users can also set up mailing list archives for e-mail lists that are hosted elsewhere. Google Groups became operational in February 2001, following Google's acquisition of Deja's Usenet archive. Deja News had been operational since March 1995. Google Groups allows any user to freely conduct and access threaded discussions, via either a web interface or e-mail. There are at least two kinds of discussion groups: forums specific to Google Groups (like mailing lists) and Usenet groups, accessible by NNTP, for which Google Groups acts as gateway and unofficial archive. The Google Groups archive of Usenet newsgroup postings dates back to 1981. On December 15, 2023, Google annou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Newsgroup
A Usenet newsgroup is a repository usually within the Usenet system for messages posted from users in different locations using the Internet. They are not only discussion groups or conversations, but also a repository to publish articles, start developing tasks like creating Linux, sustain mailing lists and file uploading. That’s thank to the protocol that poses no article size limit, but are to the providers to decide. In the late 1980s, Usenet articles were often limited by the providers to 60,000 characters, but in time, Usenet groups have been split into two types: ''text'' for mainly discussions, conversations, articles, limited by most providers to about 32,000 characters, and ''binary'' for file transfer, with providers setting limits ranging from less than 1 MB to about 4 MB. Newsgroups are technically distinct from, but functionally similar to, discussion forums on the World Wide Web. Newsreader software is used to read the content of newsgroups. Before the adoption ...

News Server
A news server is a collection of software used to handle Usenet articles. It may also refer to a computer itself which is primarily or solely used for handling Usenet. Access to Usenet is only available through news server providers. Articles and posts End users often use the term "posting" to refer to a single message or file posted to Usenet. For articles containing plain text, this is synonymous with an article. For binary content such as pictures and files, it is often necessary to split the content among multiple articles. Typically through the use of numbered Subject: headers, the multiple-article postings are automatically reassembled into a single unit by the newsreader. Most servers do not distinguish between single and multiple-part postings, dealing only at the level of the individual component articles. Headers and overviews Each news article contains a complete set of header lines, but in common use the term "headers" is also used when referring to the News Over ...

Header (computing)
In information technology, header is supplemental data placed at the beginning of a block of data being stored or transmitted. In data transmission, the data following the header is sometimes called the ''Payload (computing), payload'' or ''HTML element#body, body''. It is vital that header composition follows a clear and unambiguous specification or format, to allow for parsing. Examples * E-mail header: The text (body) is preceded by header lines indicating sender, recipient, subject, sending time stamp, receiving time stamps of all intermediate and the final mail transfer agents, and much more. * Similar headers are used in Usenet (NNTP) messages, and HTTP headers. * In a data packet sent via the Internet, the data (payload) are preceded by header information such as the sender's and the recipient's IP addresses, the Communications protocol, protocol governing the format of the payload and several other formats. The header's format is specified in the Internet Protocol, see IP h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Forté Agent
Forté Agent was an email and Usenet news client used on the Windows operating system. Agent was conceived, designed and developed by Mark Sidell and the team at Forté Internet Software in 1994 to address the need for an online/offline newsreader which capitalized on the emerging Windows GUI framework. By 1995, Agent had expanded to become a full-featured email client and remains a widely used application for integrating news and email communication on Windows. Agent supports POP email but not IMAP. Agent's Usenet features include access to multiple news servers, import/export of NZB files, threaded discussions and a highly configurable user interface which has been criticized as difficult to use. It has long supported yEnc as well as many other coding schemes, and has the capability of joining incomplete binary attachments, which is useful in the event of posting errors. In the past, a free version was offered alongside the commercial one. The free version lacked some feature ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

GNU Mailman
GNU Mailman is a computer software application from the GNU Project for managing electronic mailing lists. Mailman is coded primarily in Python and currently maintained by Abhilash Raj. Mailman is free software, licensed under the GNU General Public License. History A very early version of Mailman was written by John Viega while a graduate student, who then lost his copy of the source in a hard drive crash sometime around 1998. Ken Manheimer at Corporation for National Research Initiatives (CNRI), who was looking for a replacement for Majordomo, then took over development. When Manheimer left CNRI, Barry Warsaw took over. Mailman 3, the first major new version in over a decade, was released in April 2015. Features Mailman runs on most Unix-like systems, including Linux.

Gmane
Gmane (pronounced "mane") is an e-mail to news gateway. It allows users to access electronic mailing lists as if they were Usenet newsgroups, and also through a variety of web interfaces. Since Gmane is a bidirectional gateway, it can also be used to post on the mailing lists. Gmane is an archive; it never expires messages (unless explicitly requested by users). Gmane also supports importing list postings made prior to a list's inclusion on the service. The project was initiated in 2001 by Lars Magne Ingebrigtsen, one of the authors of Gnus, a newsreader for Emacs. It began operating publicly on 11 February 2002 after a one-month test period. , Gmane's homepage stated that it included 129,592,482 messages in its archives, from a total of 20,070 mailing lists. In July 2016, Ingebrigtsen announced that he was considering shutting Gmane down, and the web interface was taken offline. In August 2016 Gmane was acquired by Yomura Holdings. Only the message spool was transferred, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cancel Message
Control messages are a special kind of Usenet post that are used to control news servers. They differ from ordinary posts by a header field named Control. The body of the field contains control name and arguments. There are two historical alternatives to header field Control. They are not supported by contemporary software and forbidden according to RFC 5537. However, the traditional format of the subject line is widely used in addition to the Control header: the subject line consists of the word "cmsg" followed by control name and arguments. Types cancel A cancel message requests the deletion of a specific article. The body of the Control field contains one argument, the Message-ID of the article to delete. According to RFC 1036 only the author of the target message or the local news administrator is allowed to send a cancel (cancels not meeting this condition are called "rogue cancels"). To verify authorization the line (or line, if it exists) of the cancel message must ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
