📝 Describe your problem

I have set the "retries" option to "2". So I don't get any notification for single heartbeat failures.
But now I seem to receive "UP" notifications for single failures.
These are my settings:

This is the result from the log:

("Externe" and "All-Inkl" are Groups, I don't send notifications for those)

ok, thank you very much - your hint with the log file helped a lot.
The mailserver I am using and the sites which show DOWN from time to time are hosted at the same location.
It looks to me, like there are short outages which also affect the mailserver connection. This is why I don't get the DOWN emails. Need to look for a 3rd party email server.
