chore(check-for-changes.sh): Drop redundant guards (#2623)
* chore: Remove requirement for `postfix-accounts.cf`

This is an old requirement from when the change detector service was first introduced. It's no longer relevant.

* chore: Do not needlessly create `postfix-aliases.cf`

The config was created regardless to workaround early change detection support. No longer necessary to require the file to exist.

* chore: Drop guards requiring `/tmp/docker-mailserver` to exist

Legacy guards when this was the only location change detection location supported.

There does not appear to be any need for changing into this directory at the start of `check-for-changes.sh` as we use absolute filepaths (originally monitored files were checked with relative paths to this config dir).

* chore: Revise inline docs

* chore: Add change detection monitoring for extra configs

These are also handled at run-time in the current change detection support, so it makes sense to allows these config updates to also trigger change events.

chore(housekeeping): Create helpers/change-detection.sh (#2610)
* chore: Extract change-detection method to it's own helper

This doesn't really belong in `helpers/ssl.sh`. Moving to it's own helper script.

* chore: Co-locate related change-detection method from container startup

It seems relevant to migrate the related support during startup for the change detection feature into this helper.

I opted to move the call from `start-mailserver.sh` into the `_setup` call at the end for a more explicit/visible location.

* chore: Move `CHKSUM_FILE` into `helpers/change-detection.sh`

It belongs there, not in `helpers/index.sh`.

* chore: Revise inline documentation

* tests(fix): Ensure correct functionality

Presently `test/test_helper.bats` is using it's own  `CHKSUM_FILE` instead of sourcing the var for the filepath.

`test_helper/common.bash` was calling a method to check for changes, but this helper may not correctly detect letsencrypt related changes as these are not ENV rely on, but global vars handled by `helpers/dns.sh`, so that should be run first like it is for `check-for-changes.sh`.

* tests(chore): Use `CHKSUM_FILE` var from helper

* chore: `addmailuser` should use `CHKSUM_FILE` var

* chore: Update `check-for-changes.sh` log message with correct path

refactor: letsencrypt implicit location discovery (#2525)
* 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).

scripts: refactored check-for-changes.sh (#2498)
* 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.

Add changedetector functionality for ${SSL_TYPE} == manual (#2404)
Now, setups that use `SSL_TYPE=manual` will profit from the changedetector as well. Certificate changes are picked up and properly propagated.

improvement: get rid of subshell + exec in helper-functions.sh (#2401)
* get rid of subshell + exec

The new way of executing `sha512sum` should work as well as the old way
but without the clutter and possible problems the usage of subshells +
exec incurs.

Moreover, there was a misconception about array expansion. Using `""`
around an expanding array (`${ARRAY[@]}`) is quite fine (and actually
the preffered way), not because it makes the expansion _one_ string
(this would be `${ARRAY[*]}`), but it makes sure when elements are
expanded, each element has `""` around them so to speak, i.e. there is
no re-splitting of these elements.

* removed old concerns in comments

* increase test and check for changes sleep duration

fix: Restore detection of letsencrypt certificate file changes (#2326)
The `DYNAMIC_FILES` var was quote wrapped, treating all filepaths to create checksums for as a single string that would be ignored instead of processed individually.

Removed the quotes, and changed the for loop to an array which accomplishes the same goal.


* fix: Prevent unnecessary change detection event

`acme.json` change would extract new cert files, which would then be hashed after restarting services and considered a change event, running through the logic again and restarting services once more when that was not required.

The checksum entries for those cert files are now replaced with new entries containing updated checksum hashes, after `acme.json` extraction.

fix: check-for-changes.sh should not fall out of sync with shared logic (#2260)
Removes duplicate logic from `check-for-changes.sh` that is used/maintained elsewhere to avoid risk of problems, as this code is already starting to diverge / rot.

---

Previously the change detection support has had code added for rebuilding config upon change detection which is the same as code run during startup scripts. Unfortunately over time this has fallen out of sync. Mostly the startup scripts would get maintenance and the contributor and reviewers may not have been aware of the duplicate code handled by `check-for-changes.sh`.

That code was starting to diverge in addition to some changes in structure (_eg: relay host logic seems interleaved here vs separated out in startup scripts_). I wanted to address this before it risks becoming a much bigger headache.

Rather than bloat `helper-functions.sh` further, I've added a `helpers/` folder extracting relevant common logic between startup scripts and `changedetector`. If you want to follow that process I've kept scoped commits to make those diffs easier. Some minor changes/improvements were added but nothing significant.

- chore: Extract relay host logic to new `relay.sh` helper
- chore: Extract `/etc/postfix/sasl_passwd` logic to new `sasl.sh` helper
- chore: Extract `postfix-accounts.cf` logic to new `accounts.sh` helper
- chore: Extract `/etc/aliases` logic to new `aliases.sh` helper
- chore: Extract `/etc/postfix/vhost` logic to new `postfix.sh` helper

- chore: Add inline docs for Postfix configs
> These are possibly more verbose than needed and can be reduced at a later stage.
> They are helpful during this refactor process while investigating that everything is handled correctly.

`accounts.sh`: 
- Add note regarding potential bug for bare domain setups with `/etc/postfix/vhost` and `mydestination` sharing same domain value.

`relay.sh`: 
- Remove the tabs for a single space delimiter, revised associated comment.
- Add PR reference for original `_populate_relayhost_map` implementation which has some useful details.

refactor: acme.json extraction (#2274)
Split into scoped commits with messages if further details are needed, view those via the associated PR :)

**Commit Summary:**

**`check-for-changes.sh`**

- Prevent `SSL_DOMAIN` silently skipping when value has wildcard prefix `*.` (_at least this was known as a bugfix when originally committed in linked PR_).
- Improved inlined docs for maintainers.
- Additional logging for debugging.

**`helper-functions.sh:_extract_certs_from_acme`**:

- Fail if the input arg (_`$CERT_DOMAIN`, aka the FQDN_) provided for extraction is empty.
- Use `$CERT_DOMAIN` in place of `$HOSTNAME` and `$1` for a consistent value (_previously could mismatch, eg with `SSL_DOMAIN` defined_).
- The conditional is now only for handling extraction failure (_key or cert value is missing from extraction_).
- Log an actual warning or success (debug) based on outcome.
- Don't use `SSL_DOMAIN` with wildcard value for the `mkdir` letsencrypt directory name (_wildcard prefix `*.` is first stripped instead_).

**`acme_extract`** (_new python utility for `acme.json` handling_):

- Extracted out into a python script that can be treated as a utility in the `$PATH` like other helper scripts. It can now be used and optionally tested directly instead of via `helper-functions.sh`.
-Made compatible with Python 3, as Python 2 is EOL and no longer in newer versions of Debian.

HOSTNAME and DOMAINNAME setting improvements (#2175)
Centralize the collection of the HOSTNAME and DOMAINAME so that it's predictable and uniform across the various scripts (using the helper). Ensure it supports the various configurations users can have (both subdomain and without subdomain, override and no override).

---

* using _obtain_hostname_and_domainname helper + covers when not a subdomain
doc: OVERRIDE_HOSTNAME takes priority

* added tests for non-subdomain hostname + further improvements

* moved SRS DOMAINANME tests into hostname test file + Allowing DOMAINNAME ENV to override what would be automatically set
