email notifications for critical alerts Icinga1

  • I have an Icinga 1.14 farm (that I must maintain whilst migrating to Icinga2) and I can't seem to get email notifications to work for any alerts on the icinga1 side.

    I have one master and several dozen satellites. Boss wants email alerts sent for one customer's critical alerts.

    The satellites cannot send or receive email (they are in a DMZ) so all email messages need to be sent by the master.

    So is it possible to have email notifications sent from the master based on alerts originated on a satellite? Do I have to change anything on the satellite or should I focus strictly on the master's configs?
