End of last year, I've re-installed mailman3 using the virtualenv installation method on ubuntu 20.04.
Since then, the transport map (/opt/mailman/mm/var/data/postfix_lmtp) has not been updated even though, new mailing lists were created. The old mailing lists, that existed before the re-installation work perfectly fine but those created after are not accessible. Because the entries for those new lists are missing in the transport map, postfix replies with a "mail for ... loops back to myself" error.
I'm quite sure, that I did all the steps in the documentation (except that I use a slightly different apache2 vhost configuration). I double checked on the cronjobs.
crontab -u mailman -e
@daily /opt/mailman/venv/bin/mailman digests --periodic @daily /opt/mailman/venv/bin/mailman notify
- * /opt/mailman/venv/bin/mailman-web runjobs minutely 0,15,30,45 * * * * /opt/mailman/venv/bin/mailman-web runjobs quarter_hourly @hourly /opt/mailman/venv/bin/mailman-web runjobs hourly @daily /opt/mailman/venv/bin/mailman-web runjobs daily @weekly /opt/mailman/venv/bin/mailman-web runjobs weekly @monthly /opt/mailman/venv/bin/mailman-web runjobs monthly @yearly /opt/mailman/venv/bin/mailman-web runjobs yearly
Any idea, what I could have missed???
Kind regards, Nils
