we have thought a while about it and needed a solution badly. We are having several Mail2News mailing lists, which all come up with broken threading, when cross posted messages appear. The same issues as stated in the bug here: https://bugs.launchpad.net/mailman/+bug/266263
I have just added a patch and a description for the patch at launchpad.
This is a request for considering this patch as improvement and merging it. A lot of mail and news administrators would be thankful for less headaches :)
kind regards, kloschi
With or without religion, we would have good people doing good things
and evil people doing evil things. But for good people to do evil
things, that takes religion."
