and started bin/mailman start. The PostgreSQL database was initialized,
bin/mailman status showed the correct configuration location. I could
create lists and they were added in the SQL database. It would use
ipython as shell. But it would still try to send mail through localhost,
and it would still start the nntp runner. And LMTP would reject mails to
the existing lists with "mailbox unavailable". So it seems the
configuration was only used by the main process, but not by the runners.
Moving the configuration to a non-relative location fixed it.
