Hi, (back to just announcements on this list but this is one) We have scheduled an upgrade of mailman (https://lists.wikimedia.org) for: Wednesday, September 9, 2015 at 2:00:00 PM UTC ( 7:00 AM PDT, 16:00 CEST) The scheduled mainteance window is 4 hours (or less). During this time please expect all the mailing lists (web interface and email) to be down. We will shut down the old server, then sync all pending mail to the new server and bring it back up there. The upgrade includes mailman from 2.1.13 to 2.1.18 and the server OS will become a Debian jessie server and will be virtualized. More things we expect to be fixed by this (excerpts): "DMARC improvements solve issues users have with Yahoo and Outlook regarding mail." "Password reminder link is now on the roster page (private archives)." "Emails can be automatically accepted to private lists if a poster password is used" "Cookies now set the secure flag when over HTTPS" "Emails are validated more accurately. Spam prevention." "Sessions can be invalidated through logouts on administrator and moderation interfaces." refs: https://wikitech.wikimedia.org/wiki/Mailman , https://phabricator.wikimedia.org/T105756 , Will follow-up with one other mail once it's done. As said above this was supposed to be just an announcement since this list should be low volume. Discussion/comments should probably be elsewhere.If you ask me i prefer Phabricator personally because think it's more effective to have tasks and discussion in the same place.
