[pbs-devel] [PATCH proxmox-backup v4 22/43] server: notifications: send verify notifications via notification system
Lukas Wagner

Mon Apr 22 14:38:20 CEST 2024
If the `notification-mode` parameter is set to `legacy-sendmail`, then
we still use the new infrastructure, but don't consider the
notification config and use a hard-coded sendmail endpoint directly.
