Phew, what's the rationale to not support your subscribers in *any* way during this? With compatible lists addresses or at least compatible headers?
There are over 700.000(!) individual subscribers on the lists. Nearly 10.000(!) of them have more than one subscription. I bet you, subscribers who have more than 5 subscriptions number in the hundreds. Out of those you will find dozens that have complicated mail filtering going on.
You want to render this incompatible with 3 days of notice. Have you thought about the amount of work you are going to cause?
Of course we did. This was discussed two months ago[1]. The reason we're pulling the trigger now is that suse.com is switching on a DMARC policy that will break sending any emails to openSUSE mailing lists. Mailman offered a reasonable path for those emails, so we're doing the transition now with "short notice". You'd still have to deal with this even if we could wait a bit longer, but you cannot say you didn't know this was coming.
the way this is described it sounds to me that SUSE pulled the trigger on implimenting DMARC without fully considering the impact on the openSUSE community, a quite substantial impact as Henne points out.
Can someone please confirm that the Board (and it's Chair) did communicate the severe impact on the community to SUSE, and explain why it was decided to go ahead regardless of that impact?
We have been in contact with the board and SUSE IT for about a month, yes. The problem is the changes made to postings when they are distributed by the mailing list manager. We change the Subject header and prepend the listname (in square brackets) and we append a friendly footer to every posting, explaining to the recipient how to unsubscribe and contact the owner. Those changes invalidate the DKIM signature added by anyone posting to an openSUSE list. The DMARC policy would have meant "suse.com" begin rejected or quarantined by mailservers implementing DMARC. To ensure postings to openSUSE lists from suse.com addresses would continue to be accepted by all mailservers, we had two options - a) remove the listname prefix and the footer texts from all lists, thereby maintaining a valid DKIM signature, b) step up the migration to mailman which had already been in the works for quite some time.
