I configured the SMTP module. The test is working. The e-mail arrives.

I have a new module with heartbeat. When it is of-line, the error message evoked by the related rule generates a high alert. In the log the the entry is there. SMTP does not react.

It is working again. Why I don't know but who cares?

The behaviour is unstable. Only every now and than a message is sent. No trend to see.

I guess the alert is triggering, you see it under notification but the email does not arrive, correct? If so look at the logs for any error coming from the notification/smtp module. If nothing is showing up, try enabling debug mode for that module and trigger the notification. At least here the smtp notification never failed. Also ensure there are no suppression rules configured. Thanks!

Your advice was right. I had a suppression on SMTP messages per hour instead of suppression on individual rules.

I do have a SMTP issue again. I have set the heartbeat signal for a module. The rule is triggering and an alert pops-up. The e-mail message is not sent.

When I disable the heartbeat sensor of my weather station it is the same. The alert pops up but no e-mail. And this one has been working.

With debug on for the smtp module, nothing happens. I get the feeling that the trigger is not being passed to the smtp module.

@eporocrail said in SMTP issue:

Theoretically the alert popup and the smtp module use the same way to capture notifications to be sent so I doubt this is the case. Is notification/smtp showing up as running and configured in eGeoffrey/Modules? Is the test notification working fine?
Thanks

What happened I do not know but suddenly e-mail messages about a module being off-line started coming in.

Error message is saying the hostname of the smtp server configured could not be resolved. Internet or DNS down?

That could be the reason why it started working later on.
