We have been trying to set up email or telegram notifications in Icinga2 Director for a long time, but we can’t find any useful help on how to set them up or the posts are outdated.
Do we need a dedicated mail server for notifications or do we need to set up a Postfix relay host?
Could you give us tips on how to set this up successfully?
