The latest version of Zabbix (v6.4) on Ubuntu LTS 22.04 works very well with email notification. In the interest of preventing redundancy, I would like to use that same package for sending emails from other non-Zabbix custom scripts on the same server. Does anyone know what Zabbix uses to send emails?
A "sudo apt list --installed" command on a working Zabbix server doesn't list postfix, sendmail, or any other mail program I am familiar with.
