Borg_ynh didn't send any email alert on backup error

[eauchat]

Describe the bug

For some time the backup server was down, but I didn't receive any alert email that the backup failed.
I'm using the setting mailalert: errors_only.
I didn't have this problem some months ago, before the mailalert setting existed. Wondering if it's related, or not.

It's hightly recommended to make your backup when the service is stopped. Please stop synapse service with this command before to run the backup 'systemctl stop matrix-synapse.service'

Same here it stopped sending me emails for some reason....I have no idea why. It used to work. What I did was to change in config how to receive the emails, for 2 servers. From Always to only when an error occurs. Then I even changed back to Always. But it does not send any alerts of any sort.

#metoo
didn't receive the alert email on a failed attempt to login into the Borg server
