First: Sorry for my bad english. I'm not a native english-speaker, so
please ignore my mistakes. :o)
I'm running some lists with the NNTP-gateway enabled both ways. I've
noticed that when mailman posts to the newsgroup, it changes the
Message-Id. Or, I guess it's mailman and not INN. This generates
problems with threading, since one message got two message ids.
test at lists.example.com both posts and collects messages from local.test
at the news-server news.example.com. John and Anne are both subscribed
to the list and Peter prefers to use the news-server.
John posts a message to the list with subject "Hello". John's client
generates the message id <john123.456 at example.com> for that mail.
Mailman will now forward that message correctly to Anne, with the right
message id. But when Peter reads the message at the news-server, he will
see the message id <mailman.345.987 at lists.example.com>.
So far, everything looks fine for the users. But now Anne wants to make
a reply to John's post and posts a message to the list with subject "Re:
Hello". This message has the In-Reply-To-header
"<john123.456 at example.com>", since this is the message id on the mail
she recieved. Peter, who are still using NNTP, will not be able to find
the message <john123.456 at example.com>, since it has been renamed to
<mailman.345.654 at lists.example.com> on the news-server. Peter's
newsreader will then create a new thread for the reply.
Are there any way I can let all the users of my lists recieve the same
message ids, so my news-reading users will be able to get the threads
Thak you in advance.
