The openstack, openstack-dev, openstack-sigs and openstack-operators mailing lists were replaced by openstack-discuss. Starting now the old lists are no longer receiving new posts, but their addresses are aliased to the new list for the convenience of anyone replying to an earlier message. If you happen to notice one of the old list addresses in a reply you're writing, please take a moment to update it to the correct one. Here follow some brief notes on the nature of this new list: 1. We have documented[*] subject tags we want to use. Most of our current needs are probably already covered there, but if you notice something missing you can correct it by posting a change for code review to the doc/source/open-community.rst file in the openstack/project-team-guide Git repository. Because we're interested in moving to Mailman 3 as our listserv in the not-too-distant future and the upstream Mailman maintainers decided to drop support for server-side topic filters, you'll need to set up client-side mail filtering if you're only interested in seeing messages for a subset of them. 2. Remember there is no Subject header mangling on this list, so if you want to perform client-side matching it's strongly recommended you use the List-Id header to identify it. You'll likely also notice there is no list footer appended to every message. Further, the From and Reply-To headers from the original message are unaltered by the listserv. These changes in behavior from our previous lists are part of an effort to avoid creating unnecessary DMARC/DKIM violations. A mailreader with reply-to-list functionality is strongly recommended. If you're unfortunate enough not to be using such a client, you may be able to get away with using reply-to-all and then removing any irrelevant addresses (making sure to still include the mailing list's posting address). 3.
