Learn why this is important<https://aka.ms/LearnAboutSenderIdentification> Is SELinux enabled on your Ubuntu install? If so, you may need to change it from Enforcing mode to Permissive mode in the /etc/selinux/config file. SELinux will block many of the commands run by Xymon unless they are all explicitly granted permission by SELinux.
