Konfiguration
Die Datei
sudo vi /etc/opendmarc.conf
bearbeiten und folgende Parameter anpassen bzw. hinzufügen:
AuthservID OpenDMARC Socket local:/var/spool/postfix/opendmarc/opendmarc.sock TrustedAuthservIDs mail1.kirner.or.at ## Optional #RejectFailures true ## You may want OpenDMARC to ignore SMTP clients that are successfully ## authenticated via SMTP AUTH. IgnoreAuthenticatedClients true ## This will reject emails that don't conform to email header standards ## as described in RFC5322. For example, if an incoming email doesn't ## have From: header or date: header, it will be rejected. RequiredHeaders true ## This will cause OpenDMARC to perform a fallback SPF check itself when ## it can find no SPF results in the message header. SPFSelfValidate true
Das Verzeichnis für den Socket muss noch angelegt und für den Benutzer postfix schreibbar gemacht werden:
sudo mkdir -p /var/spool/postfix/opendmarc sudo chown opendmarc:opendmarc /var/spool/postfix/opendmarc sudo chmod 750 /var/spool/postfix/opendmarc/ sudo adduser postfix opendmarc
Zum Abschluss den Service neustarten:
sudo systemctl restart opendmarc.service
