I'm Ian Kelling, part of the FSF tech team that maintains the lists.nongnu.org server.
The server is sending mail using a new ip which is causing a higher than average number of mail servers telling us to retry and send later as they hopefully decide we are legitimate. The only big provider doing this is yahoo, others are small enough that if messages aren't coming as normal, you should probably be able to get your email server sysadmin to open the pipe. Yahoo has a long history of being unfriendly to mailing list messages in various ways, so its not totally unusual. My plan is to monitor the situation and if it doesn't improve in the next day or so, I will give the new server its old ip and see if that fixes it. I specifically wanted to say something on qemu-devel since it is the most active list. General information about the upgrade: There was a ~25 minute downtime while I upgraded the server, but since email servers naturally just queue and retry, that shouldn't have lost any messages. If you want to keep updated on things like that, mainly watch https://quitter.im/fsfstatus We don't handle all list issues though. Someone on this list manages the list settings, moderation, list membership, etc. Savannah volunteers also help with managing GNU Mailman. More information is here: https://savannah.nongnu.org/maintenance/NotSavannahAdmins/ Theres been a lot of small improvements from the upgrade. Some I find notable are: the web interface is now using tls 1.2. Also, the configuration and upgrade process is also now well documented and automated, which helps us to make more improvements and keep the software up to date. I look forward to eventually integrating new software, for example a new archive interface while also maintaining and improving the existing software. When we start looking deeper into new software, we will definitely seek input here. Of course, input is welcome anytime.
