Noch ein Followup, FYI und um zu vermeiden, daß jetzt Leute an bofh.it
posten und vielleicht Larsi (falsch) zitieren.

Genauer macht es einen Unterschied, ob ein News server standalone ist,
wie Gmane, oder tatsächlich in's Usenet eingebunden ist, wie
bofh.it. Daher habe ich nochmal nachgefragt:

That is, if I understand correctly, it's sometimes necessary to
specifically convert multiposts into crossposts ?

And that would then be the only reason you can imagine right now why
conditional MID rewriting might make sense for Mailing Lists/News
gateways ?

Thanks a lot, Bruno.

It's not generally possible to convert multiposts, because you don't
know that it is a multipost until you see the second copy.  By that
time it's too late to do anything other than rewrite the Message-ID.

Well, if the list is supposed to be distributed to the general Usenet,
then there's another reason.  it.lists.linux-kernel and
de.lists.linux-kernel might really be the same mailing list.  Then
news servers that carry both these Usenet news groups will look very
strange -- they won't have messages for these groups based on which
group got the messages in question first.

But if you're not a Usenet news server (and Gmane isn't a Usenet news
server), then that's basically the only reason.

Also, in summa, während das MID rewriting bei bofh.it durchaus Sinn
machen kann, und daher in diesem Fall eben nicht am Gateway vorbei
gepostet werden sollte, ist ein rewriting bei Gmane eben nicht nötig.

Gruss, Bruno.
