The `Newsgroups:' line isn't limited to just one group--an article can be posted in a list of groups. For instance, the line
Newsgroups: sci.space,comp.simulation
posts the article to both the groups sci.space and
comp.simulation. It's usually safe to crosspost to up to three
or four groups. To list more than that is considered "excessive
noise."
It's also suggested that if an article is crossposted a `Followup-To:' header be included. It should name the group to which all additional discussion should be directed to. For the above example a possible `Followup-To:' would be
Followup-To: sci.space
which would make all followups automatically be posted to just
sci.space, rather than both sci.space and
comp.simulation. If every response made with a newsreader's
"followup" command should go to the person posting the article no
matter what, there's also a mechanism worked in to accommodate. The
Followup-To: header should contain the single word
`poster':
Followup-To: poster
Certain newsreaders will use this to sense that a reply should never be posted back onto The Net. This is often used with questions that will yield a summary of information later, a vote, or an advertisement.
