[MariaDB discuss] Setting up primary-secondary replication

Greetings! I'm trying to set up a backup email server using Ubuntu 23.10 Server. I want to replicate my MariaDB databases from the primary email server to the secondary, but whenever I add the line log-bin = /var/log/mysql/master-bin to /etc/mysql/mariadb.conf.d/50-server.cnf MariaDB fails to restart. I've looked for help online, but haven't had any luck. Can anyone help? Further details available on request.
