* docs: Debugging - Delivery failure from service downtime
Services may be temporarily down, such as when restarted when certificates are updated due to the `check-for-changes.sh` service. This is another known source of intermittent delivery failures.
* improvide docs about how to work with logs
Most importantly,
1. I added information on the recently adopted `less` / `nano`
2. I added information about `/var/log/mail/`
* fix typos
* Apply suggestions from code review
* Update docs/content/config/debugging.md
