Standard for Interchange of USENET Messages
STATUS OF THIS MEMO
This document defines the standard format for the interchange of
network News messages among USENET hosts. It updates and replaces
RFC-850, reflecting version B2.11 of the News program. This memo is
disributed as an RFC to make this information easily accessible to
the Internet community. It does not specify an Internet standard.
Distribution of this memo is unlimited.
1. Introduction
This document defines the standard format for the interchange of
network News messages among USENET hosts. It describes the format
for messages themselves and gives partial standards for transmission
of news. The news transmission is not entirely in order to give a
good deal of flexibility to the hosts to choose transmission
hardware and software, to batch news, and so on.
There are five sections to this document. Section two defines the
format. Section three defines the valid control messages. Section
four specifies some valid transmission methods. Section five
describes the overall news propagation algorithm.
2. Message Format
The primary consideration in choosing a message format is that it
fit in with existing tools as well as possible. Existing tools
include implementations of both mail and news. (The notesfiles
system from the University of Illinois is considered a news
implementation.) A standard format for mail messages has existed
for many years on the Internet, and this format meets most of the
needs of USENET. Since the Internet format is extensible,
extensions to meet the additional needs of USENET are easily made
within the Internet standard. Therefore, the rule is adopted that
all USENET news messages must be formatted as valid Internet mail
messages, according to the Internet standard RFC-822. The USENET
News standard is more restrictive than the Internet standard,
