CMK version: 2.2.0 Raw Edition
OS version: docker container checkmk/check-mk-raw:2.2.0
I want checkmk to be able to send email notifications. To do this I have read Notifications - via Email, SMS, Ticketsystems and more, but the information there is quite sparse.
In theory the task is quite simple. I just want to use an existing mail account we have at IONOS and use this to send notifications. IONOS provides this info:
Server: smtp.ionos.de, Port: 465, Connection type: SSL/TLS
And together with my email address and password sending emails should by fairly simple.
In practice I have tried a lot of guides on how to configure sendmail, postfix or mailx for a few hours now and nothing worked. I don’t even get error messages or logs. It just doesn’t do anything. Most guides assume you already have a local mail server, which we don’t. I don’t actually know anything about SMTP server configuration and most of this seems so overcomplicated when all I want is just to send a mail via SMTP.
Can somebody please assist in configuring this?
