* tests(fix): Increase some timeouts
Running tests locally via a VM these tests would fail sometimes due to the time from being queued and Amavis actually processing being roughly around 30 seconds.
There should be no harm in raising this to 60 seconds, other than delaying a failure case which will ripple through other time sensitive tests.
It's better to pass when functionality is actually correct but just needs a bit longer to complete.
* tests(fix): Don't setup an invalid hostname
During container startup `helpers/dns.sh` would panic with `hostname -f` failing.
Dropping `--domainname` for this container is fine and does not affect the point of it's test.
---
It's unclear why this does not occur in CI. Possibly changes within the docker daemon since as CI runs docker on Ubuntu 20.04? (2020).
For clarity, this may be equivalent to setting a hostname of `domain.com.domain.com`, or `--hostname` value truncated the NIS domain (`--domainname`) of the same value.
IIRC, it would still fail with both options using different values if `--hostname` was multi-label. I believe I've documented how non-deterministic these options can be across different environments.
`--hostname` should be preferred. There doesn't seem to be any reason to actually need `--domainname` (which is NIS domain name, unrelated to the DNS domain name). We still need to properly investigate reworking our ENV support that `dns.sh` manages.
---
Containers were also not removing themselves after failures either (missing teardown). Which would cause problems when running tests again.
* chore: Normalize white-space
Sets a consistent indent size of 2 spaces. Previously this varied a fair bit, sometimes with tabs or mixed tabs and spaces.
Some formatting with blank lines.
Easier to review with white-space in diff ignored. Some minor edits besides blank lines, but no change in functionality.
* fix: `setup.sh` target container under test
Some of the `setup.sh` commands did not specify the container which was problematic if another `docker-mailserver` container was running, causing test failures.
This probably doesn't help with `test/no_container.bats`, but at least prevents `test/tests.bats` failing at this point.
* consistently name functions (starting with `_`) in `start-mailserver.sh`
Most of the functions that execute the different stacks during startup
were not prefixed with `_`, but all our other functions are. This has
now been fixed.
* cleanup in `start-mailserver.sh`
I adjusted the comments for all sections in the start script so they are
properly displayed again.
Dovecot master accounts can now be configured in DMS via `setup.sh`.
A master account is useful for administration purposes, or to perform mailbox backups of every user account over IMAP.

Removed typo "logs".
Removed warning that Docker volumes are strongly recommended, as this can lead new users in the wrong direction (bind mounts are now the default).
Altering line 8, mentioning the default of bind mounts.
* chore: Remove `DATABASE` fallback ENV
This was introduced without any mention or need, thus removing until a real use-case requires it.
* chore: Remove `USER_DATABASE` fallback ENV
Likewise, nothing requires this to be customizable.
* chore: Consistently use single quote strings
* chore: Extract letsencrypt logic into methods
This allows other scripts to share the functionality to discover the correct letsencrypt folder from the 3 possible locations (where specific order is important).
As these methods should now return a string value, the `return 1` after a panic is now dropped.
* chore: Update comments
The todo is resolved with this PR, `_setup_ssl` will be called by both cert conditional statements with purpose for each better documented to maintainers at the start of the logic block.
* refactor: Defer most logic to helper/ssl.sh
The loop is no longer required, extraction is delegated to `_setup_ssl` now.
For the change event prevention, we retrieve the relevant FQDN via the new helper method, beyond that it's just indentation diff.
`check-for-changes.sh` adjusted to allow locally scoped var declarations by wrapping a function. Presently no loop control flow is needed so this seems fine. Made it clear that `CHANGED` is local and `CHKSUM_FILE` is not.
Panic scope doesn't require `SSL_TYPE` for context, it's clearly`letsencrypt`.
* fix: Correctly match wildcard results
Now that the service configs are properly updated, when the services restart they will return a cert with the SAN `DNS:*.example.test`, which is valid for `mail.example.test`, however the test function did not properly account for this in the regexp query.
Resolved by truncating the left-most DNS label from FQDN and adding a third check to match a returned wildcard DNS result.
Extracted out the common logic to create the regexp query and renamed the methods to communicate more clearly that they check the FQDN is supported, not necessarily explicitly listed by the cert.
* tests(letsencrypt): Enable remaining tests
These will now pass. Adjusted comments accordingly.
Added an additional test on a fake FQDN that should still be valid to a wildcard cert (SNI validation in a proper setup would reject the connection afterwards).

This PR does two small things:
1. The log level, in case it is unset, will now be "calculated" from
`/etc/dms-settings` and not always default to `info`. This way, we
can ensure that more often than not, the log level the user chose
when starting DMS is used everywhere.
2. I noticed that the way I obtained the log level could be used to
obtain any env variable's log level. I therefore added a function to
`utils.sh` in case we use it in the future.
* first adjustments to use Fail2Ban with nftables
* replace `iptables` -> `nftables` and adjust tests
nftables lists IPs a bit differently , so the order was adjusted for the
tests to be more flexible.
* line correction in mailserver.env
* change from `.conf` -> `.local` and remove redundant config
* revert HEREDOC to `echo`

* refactored `check-for-changes.sh`
I refactored `check-for-changes.sh` and used the new log. `_notify` can
therefore be deleted as it is used no more.
I opted to source `/etc/dms-settings` as a whole to
future-proof the script. When the DNS adjustments PRs (that do not exist
by now but will exit in the future) are done, we can then remove
`_obtain_hostname_and_domainname` because we're already writing the
variables to `/etc/dms-settings`. I left instructions in the script in
the form of TODO comments.
Because we now log the date for all messages of the changedetector, we
need to `tail` a bit more log than before.
* disabled unreliable test
The "quota exceeded" test is unreliable and failed too often lately for
my taste. Therefore, I'd like to disable it because there is no use in
having such a test.
* corrected PR id in URL
* refactored `daemon-stack.sh`
A new method was introduced to uniformaly start daemons and log output
accordingly. The methods for daemon start were renamed (plural ->
singular), therefore the adjustments in `start-mailserver.sh`.
* cleaned Fetchmail setup from `daemon-stack.sh`
Not sure why, but the Fetchmail setup was somehow happening in
`daemon-stack.sh` - this is not supposed to be the case. I relocated the
setup into `setup-stack.sh`, where it belong.
* delete old, unnecessary script in `target/bin/`
These are unused leftovers from the last commit, that relocated the
setup of Fetchmail into `setup.stack.sh`.
* corrected changedetector function name
* Apply suggestions from code review
* adjusted `debug-fetchmail` script
It is absolutely fine to source `setup-stack.sh` because sourcing the
script does not execute a single function (by desing of the script).
This way, we retain functionality.
* praise be ShellCheck
* added `log.sh` to `debug-fetchmail` as a dependency
* final cleanup
