You can prevent most Usenet archives from recording your newsgroup postings. Newsgroup
archives save all messages on
the Usenet, and other people will be able to retrieve your postings months and
years later. You may not want this to happen for a couple of different reasons:
- Time. Your message is an informational type with a short time span
of interest, like a notice for a weekly seminar, and doesn't add long
value to the Usenet.
- Personal. You are discussing sensitive
or personal subjects, or have other privacy reasons.
You can prevent
most newsgroup archives from saving your postings by putting the following command
the very first line, without any preceding blank lines or spaces:
Some Usenet news readers
enable you to set a list of standard x-headers to every posting. If you wish,
you can configure the "x-no-archive" option as one of these headers, so that it
gets included in every one of your postings.
However, remember that your
message will still be distributed across the Internet to news servers around
the world, and anyone around the world will still be able to read it as long
carries it. Moreover, not all archives honour the x-no-archive option, and will
archive your message anyway. Furthermore, if anyone replies to your message,
includes it inline to their reply without a x-no-archive in their own message,
then your message will be included in the archives as part of their reply.
