Switch to rsyslog:

In /etc/mosquitto/mosquitto.conf:

log_dest syslog
log_facility 0
log_type error
log_type warning
log_type information
log_timestamp true

In /etc/rsyslog.conf:

local0.*                        -/var/log/mosquitto/server.log

Then:

systemctl restart rsyslog.service
systemctl restart mosquitto.service

Of course, you can change the facility (from local0) and the file name to whatever you want
Pay attention to directory permissions to make sure that syslog can write the file.
