That's why lists.fedoraproject.org and lists.opensuse.org are set up the way they are, too. As for renaming mailing lists, I think we should deduplicate the "CentOS" name out of the lists, so the mapping would be like so: * CentOS-devel at centos.org -> devel at lists.centos.org * CentOS at centos.org -> general at lists.centos.org * CentOS-{lang}@centos.org -> general-{lang}@lists.centos.org The rest are straightforward, similar to these. When I helped with the migration to mailman3 on the openSUSE side, we did a similar move and made sure the old addresses redirect to the new ones. -- 真実はいつも一つ！/ Always, there's only one truth!
