Noch ein Followup, FYI und um zu vermeiden, da� 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 tats�chlich in's Usenet eingebunden ist, wie bofh.it. Daher habe ich nochmal nachgefragt: [quote "Meine Frage"] > So, no, Gmane is never going to start doing unconditional Message-ID > rewriting.

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. > 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 ? 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. [quote end "Larsi's Antwort"] Also, in summa, w�hrend 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 n�tig. Gruss, Bruno.
