I’ve got the mail settings all setup for smtp in the global alert settings with our smtp server, the send alerts to default contact turned off, the alert transport type is set as mail and set to send to a specific email address however librenms does not seem to be sending the alert emails. I see the alerts based on the rules I have setup, but no email notification. I didn’t edit the mail.php file and only configured the smtp settings on the web UI. Am I missing something?
Any help is appreciated. Thx
Have you tried the testing docs for alerting? Testing - LibreNMS Docs
yep. here’s the result
“select * from users where exists (select * from roles inner join assigned_roles on roles.id = assigned_roles.role_id where users.user_id = assigned_roles.entity_id and assigned_roles.entity_type = ‘App\Models\User’ and name in (‘admin’, ‘global-read’) and (assigned_roles.scope is null) and (roles.scope is null)) and not email = ‘’” // vendor/laravel/framework/src/Illuminate/Database/Query/Builder.php:3919

still not getting the email alert
If you edit LibreNMS/Util/Mail.php on line 118 and change $mail->SMTPDebug = 0; to $mail->SMTPDebug = 1;
Then re-run the test.
Once done, run git checkout LibreNMS/Util/Mail.php
no change. here’s the full debug result from test-altert.php

Can you share your mail config (feel free to obfuscate the details). the change I said to make should have spat some debug info out when trying smtp like this:
librenms@utils:~$ ./scripts/test-alert.php -r 4 -h 4
Issuing Alert-UID #56/1:
:: Transport mail => 2023-12-15 23:47:28 SMTP ERROR: Failed to connect to server: Connection refused (111)
2023-12-15 23:47:28 SMTP Error: Could not connect to SMTP host. Failed to connect to server
OK
It could also mean that mail is being accepted via the mail server so have you checked your smtp logs?
Have you made sure the from address and name is valid in Settings → Alerting → Email Options?
I’ve tried multiple valid email address’ and even tried a gmail smtp server with no luck
Is your install up to date?
Honestly, because it’s not showing any debug it must not even be getting to trying to send mail via smtp if you have made the change to that file that I mentioned?

yep. I even ran the ./daily.sh to make sure it was up to date. I did build this server from the ovf template instead of from scratch. Maybe I’ll try building a new one from a fresh install
What’s the output of validate?
