I'm getting occasional alerts with the above warning from lfd / config server firewall
Uptime: 7221 seconds

Executable: /usr/sbin/opendkim

COmmand line:
/usr/sbin/opendkim -x /etc/opendkim.conf -u opendkim -P /var/run/opendkim/opendkim.pid -p inet:8891@localhost

Network connections by the process (if any):
tcp: 127.0.0.1:8891 -> 0.0.0.0:0

We're using dkim to sign outgoing mail.

Is this something to worry about - or should I add it to /etc/csf/csf.pignore

Many thanks

Looks like the daemon that signs your mails with DKIM. Nothing to worry about(?). Unless you didn't install opendkim

Thanks - I did. I hadn't really realised I'd get alerts for everything that runs for a long period. Added to csf.pignore
