Fedora mailing lists are using fedmsg archiver for it's mailing lists without it the postorius page for existing mailing lists throws 500.
1.0.0 has one new dependency that isn't available in EPEL9 mailman3-fedmsg-plugin-schemas. This is currently in review process
mailman3-fedmsg-plugin-schemas
To make it working for now, I have both the packages build in el9-infra tag.
el9-infra
This is now in stable
