Hi,
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."

Will follow-up with another mail once it's done.
re: mailman upgrade
Unfortunately not all things worked as planned during today's migration attempt.
Some rsync/import scripts took longer than anticipated. We were trying to do it in 2 steps; one rsync from server to server and another local one in an import script. The tests we had run focused on the server-server transfer.
To speed things up we stopped the ongoing local rsync to replace it with an "mv". Due to human error and a trailing slash in a script, things were moved around the wrong way.
While trying to fix this we eventually ran out of time to stay within the scheduled window so we reverted to sodium.
For right now everything is as it was before.
Sorry for that, will try again, likely next week. Will follow-up with a new date and better strategy for copying.
There will be another scheduled maintenance window for this upgrade at:
Friday, September 18, 2015 at 2:00:00 PM UTC (Friday, September 18, 2015 at 7:00:00 AM PDT)
for 3 hour mails to lists will not be delivered and i will follow-up once this is over.
Thank you,
Happy to announce that the mailman migration is over. We are now on version 2.1.18 and running on a jessie machine, fermium.
Here is a summary of changes that are relevant to users and list admins:
Administrators / Moderators
- Emails are validated more accurately. Spam prevention. - Poster password added. Allows users who may meet moderation standards to automatically have their emails accepted. - Cookies now set the secure flag when over HTTPS (default). - Sessions can be invalidated through logouts on administrator and moderation interfaces.
Users
- DMARC improvements solve issues users have with Yahoo and Outlook regarding mail. This isn't done yet but unblocked with the new version. - 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 provided by list administrators.

Nice! Congrats on the successful migration and upgrade. :-) I also want to thank you and the others who worked on this. Mailing lists continue to be an important part of Wikimedia's infrastructure.
