I have a run into a weird roadblock in implementation. I’ve setup a host, some users, some user groups. When the host goes down I see the following in the error log (/var/log/icinga2/error.log) for every user in the userGroup
[2019-07-02 13:55:39 -0400] warning/PluginNotificationTask: Notification command for object ‘TEST_SERVER’ (PID: 2429, arguments: ‘/etc/icinga2/scripts/mail-host-notification.sh’ ‘-4’ ‘172.17.22.62’ ‘-6’ ‘’ ‘-b’ ‘IcingaAdmin’ ‘-c’ ‘test’ ‘-d’ ‘2019-07-02 13:55:39 -0400’ ‘-f’ ‘Icinga 2 HCS Monitoring’ ‘-i’ ‘https://172.17.22.61/icingaweb2’ ‘-l’ ‘TEST_SERVER’ ‘-n’ ‘TEST_SERVER’ ‘-o’ ‘PING OK - Packet loss = 0%, RTA = 0.35 ms’ ‘-r’ ‘user1@company.com’ ‘-s’ ‘UP’ ‘-t’ ‘CUSTOM’ ‘-v’ ‘false’) terminated with exit code 1, output: A Sender: field is required with multiple addresses in From: field.

. . . message not sent.
Sending to one user works fine. But not multiple users.

}
