- Scheduled, encrypted backups to S3, SFTP, REST or a local folder (new restic-mailcow container)
- Restore of mailboxes and whole domains in the UI, also deleted ones, for admins and domain admins
- Scope set by RESTIC_BACKUP_MODE in mailcow.conf (all, data, config)
- Optional backup before updates (update.sh), helper-scripts/restic.sh for a full restore
The HTTP-to-HTTPS redirect server block bound `listen [::]:{{ HTTP_PORT }}
default_server` unconditionally, while every other IPv6 listen directive in
this template is guarded by `{% if ENABLE_IPV6 %}`. On hosts where IPv6 is
disabled at the kernel level, nginx cannot bind `::` and fails to start.
This only triggers when HTTP_REDIRECT is enabled and ENABLE_IPV6 is false,
which is why it survives testing with ENABLE_IPV6=false alone.
Guard the directive like the other six IPv6 listeners in the template.
