I have made a new installation of mailman using https://www.howtoforge.com/how-to-install-and-configure-mailman-with-postfix...

This is on an Ubuntu 18.04 server hosted by IONOS

I get all the way through but when I input the start command sudo /etc/init.d/mailman start I get the error sudo: /etc/init.d/mailman: command not found

Any ideas please?

Ubuntu 18.04 uses mostly systemd. Try: sudo service mailman start or sudo systemctl start mailman

Kind regards, Christian Mack
