The problem
Hi
I am currently run LibreNMS in a new and fresh Debian 12 installation.
I have postfix configured with smtp gmail and when I sent mail from command line, like:
echo teste | mail -s teste [email protected];tail -f /var/log/mail.log everything works fine and I can see the mail in the mail.log and the mail arrived in my gmail boxmail.
So, in the Global Settings → Alerting → Email Options I tried the 3 modes available but when click test mail, back there in Alerts → Alert Transports nothing happens!
I already test it with mail in mail options, sendmail, external smtp with TLS and autenthication and for the last, try it to use the actual postfix installation in the same server where librenms is installed.
Nothing at all.
It’s even showing up in the /var/log/mail.log.
I can’t figure out what is wrong!

Hi
I already tried.
No change at all!
As I wrote before:
" I have postfix configured with smtp gmail and when I sent mail from command line, like:
echo teste | mail -s teste [email protected];tail -f /var/log/mail.log everything works fine and I can see the mail in the mail.log and the mail arrived in my gmail boxmail."
But in WEB UI the information was fullfil but tried to test nothing happens
Yeah ok so some things are working at least, wonder if you try another email thats not gmail to test? It’s been working fine for me going to our own mail server and emails without troubles via the GUI side.
Also experiencing a very similar issue on a clean install of Debian 12. I press the test email button on the transport the first one comes through. then another click at about 30 seconds later no email even though the test mail sent successfully appears. I reboot a server it shows in the alerts but no email alert is sent. I am using the default rules and no custom ones all assigned to the transport.
Please could you advise? I haven’t found anything on the forums describing this behaviour. this is the first post I have seen with another Debian 12 instance having the same issue:
