How the Usenet News Protocols Work
How the Usenet News Protocols Work
There is a problem with the newsgroups header in a message sent via e-mail. Different systems use this header in two different ways:
1 -- To indicate that this message has also been sent via Usenet news to the indicated newsgroups.
2 -- To indicate that this is a personal reply, sent only via e-mail, to a message posted on the indicated newsgroups.
Because of this problem, it is better to use the Posted-To header in e-mail to indicate that a message has also been sent to certain newsgroups, and e-mail recipients should ignore any newsgroups heading in an e-mail message.
A FIGURE shows how new articles are forwarded from server to server in Usenet News.
A server tells its adjacent servers which items it offers, the server requests those it has not already got via another route.
