Hi! As you might have noticed, a bunch of big Mail-Hosters have introduced new, even stricter, requirements. Primarily it's Microsoft, but others seem to already have followed suit. So we had to configure the list to send all mails as coming from the list itself. At least to me this seems highly annoying and makes it hard at times to immediately see who the mail is even from. mailman2 has no good way to deal with that in a more reasonable way. Mailman3 is already set up, and can be migrated to at a moments notice. The only problem with it is that I really don't like the new archives. It has ways to better deal with it, like better DMARC/SPF/... support in general, and support for ARC signing. As an example, I already migrated nut-devel: https://lists.ffmpeg.org/archives/list/nut-devel@ffmpeg.org/latest Sooner or later, we will have to migrate no matter what. Python2 is on its way out, and we will have to upgrade to an OS version that does not ship it anymore eventually. So the question is, should I just migrate ffmpeg-devel, and if that goes well, pull over all the other lists as well? In theory the migration should go without anyone noticing. It worked for nut-devel, but that's not exactly the most active list. Timo
