Let's chat about centos mailing lists !
https://lists.centos.org is powered by mailman package, available in CentOS 7 , itself going EOL next year.
There is no packaged (yet) mailman3 stack (more components than simple mailman 2 stack).
Options :
# use mailman2 package from RHEL8 That means (in theory) that we can just reinstall the machine with RHEL8, and use the package that is available in AppStream repository: mailman.x86_64 3:2.1.29-12.module+el8.5.0+13466+327eb9f3.2 Normally that should be more or less (to be tested though) transparent migration, but as that module is still relying on python2 itself, we don't know when it will itself go EOL in RHEL8 (BaseOS should be 10y but apps in AppStream can have a shorter TTL)
# migrate to mailman3 Clearly much more work to do including see if the mailman3 stack maintainer can branch to epel9 and then we can reuse it. Also time to investigate how to import previous archives from mailman2 to mailman3 but should be doable (needs time to investigate and a PoC)
# something else ?
All comments, opinions are welcome and let's discuss it in advance and not wait next year when machine will be powered off
Kind Regards,
