I have sucesfully set up LibreNMS for all my devices and I love it so far.
The one thing I cannot resolve several days and I dont know how to proceed further is email alerts. I have sucesfully set up transport rule, default contact, test mails are going through OK no problem.
But when I get an alert, no email is sent out. However when I acknowledge an alert, I get an ACK email about the alert. So by this I think that emailing is set up correctly, I can see that the transport rule is set on all alerts because it is the default one.
I have tried bilion of settings combinations such as use only default contact and several other combinations, but the mail never arrives.
Ive tried to run test-template.php, but I dont know the alerts.rule_id and seems Iam dumb enough to get past this and get it.
Ive run validate.php in GUI and everything is OK, no errors. I have read several forum topics here and seems like that everybody resolved their issue with emailing in their original way and nothing worked for me (e.g. correct timezone,…).
Could you please point me out what to look for next?
Running latest version of LibreNMS, master update channel, mailing is set up via SMTP to my Microsoft 365 Exchange Online via connector (and this is known good config working fine - test email going through OK).
Thanks a lot
