Hi there,
I have icinga2 with icingaweb2 basic setup. i would like to setup email notifications for a specific service.
I realized that the mailutils was not installed so i have installed it. There is an internal exchange 2007 in the lan so i set the posfix to use relay. When I test to send email from commandline it always fails.

This is my /etc/posfix/main.cf

Debian specific: Specifying a file name will cause the first
line of that file to be used as the name. The Debian default
is /etc/mailname.

Does posfix first need to be able to send emails before icinga can use it right?
thank you
