Reference distribution: Debian GNU/Linux 12 Bookworm.

apt install opendmarc

OpenDMARC requires a backend database, it can be confifgured automatically with dbconfig-common.

The /usr/sbin/opendmarc daemon should be running, the service is controlled by systemd:

systemctl status opendmarc.service

Se si desidera che il demone sia in ascolto sul una porta TCP invece che su un socket si modifica il file /etc/opendmarc.conf:

#Socket local:/run/opendmarc/opendmarc.sock
Socket inet:8893@127.0.0.1
