* chore: Detect missing final newline in configs read
These lines will be not be processed by `read`, emit a warning to raise awareness.
* fix: Ensure parsed config has final newline appended (when possible)
This functionality was handled in `accounts.sh` via a similar sed command (that the linked references also offer).
`printf` is better for this, no shellcheck comment required either.
We additionally don't attempt to modify files that are read-only.
* fix: Ensure parsed configs have CRLF to LF corrected (where possible)
Likewise, this runtime fix was only covering two config files. It now applies to all callers of this method.
* fix: Sanitize `postfix-master.cf` via helper
This feature should have been using the helper to avoid user error from their config updates accidentally introducing subtle breakage implicitly (due to CRLF or missing final newline).
* tests: Add test cases for new helpers
* tests: `rm` is redundant when using `BATS_TEST_TMPDIR`
This temporary directory is created and removed implicitly. Even after a test failure.
* chore: Remove old `postfix-virtual.cf` migration logic
This was introduced in 2018, there should be no one needing to rely on this anymore?
* tests: Remove comment on sed failure concern
* chore: Add entry to `CHANGELOG.md`
* Apply suggestions from code review

Some deployment scenarios are not compatible with `5000:5000` static vmail user with `/var/mail`. This feature allows adjusting the defaults to a UID / GID that is compatible.

* add new home dir for Dovecot
I tried changing the mail dir, but this is a _very_ disruptive change,
so I took approach 3 on
<https://doc.dovecot.org/configuration_manual/home_directories_for_virtual_users/>,
whereby the home directory is now inside the mail directory.
The MDBOX/SDBOX formats are not touched by this change. The change
itself could be considered breaking though.
* adjust Sieve tests accordingly
* Update target/dovecot/10-mail.conf
* Update target/dovecot/auth-passwdfile.inc

* outsourcing env variable setup
This commit contains major parts of the work of refactoring the setup
and usage of environment variables. It outsources the setup into its own
script and provides dedicated functions to be executed at a later point in time.
A **new** env variable was added: `USER_PROVISIONG` which provides a
better way of defining which method / protocol to use when it comes to
setting up users. This way, the `ENABLE_LDAP` variable is deprecated,
but all of this is backwards compatible due to a "compatibility layer", a function provided by the new variables script.
This is not a breaking change. It mostly refators internal scripts. The
only change facing the user-side is the deprecation of `ENABLE_LDAP`. We
can prolong the period of deprecation for this variable as long as we
want, because the new function that ensures backwards compatibility
provides a clean interface for the future.

* chore: Split vhost helper method and use filepath vars
- Helpers `accounts.sh` and `aliases.sh` can move their vhost code into this helper.
- They share duplicate code with `bin/open-dkim` which will also leverage this vhost helper going forward.
* chore: Sync vhost generation logic into helper
- Chunky commit, but mostly copy/paste of logic into a common method.
- `bin/open-dkim` additionally wrapped relevant logic in a function call and revised inline docs.
* chore: Include LDAP vhost support
- Revises notes for LDAP vhost support.
- This now ensures LDAP users get vhost rebuilt to match the startup script for when change detection support is enabled.
- `bin/open-dkim` will additionally be able to support the default `DOMAINNAME` var (set via `helpers/dns.sh`) for LDAP users instead of requiring them to provide one explicitly.
* chore(`bin/open-dkim`): Ensure `DOMAINNAME` is properly set
- This will ensure LDAP users insert the same `DOMAINNAME` value as used during container startup.
- The container itself should panic at startup (during `helpers/dns.sh`) if this isn't configured correctly already, thus it should not introduce any breaking change to users of this utility?
* chore: Set the 2nd value as blank `_`
Line is split by a delimiter such as white-space (or via IFS: `|`), the blank `_` var is to indicate we're not interested in that value, but still leverage how `read -r` works, instead of splitting the var ourselves first thing.
* chore: Remove shellcheck disable lines
No longer applicable with the switch to `_`
* chore(`aliases.sh`): Filepath to local var `DATABASE_VIRTUAL`
* chore(`accounts.sh`): Filepath to local var `DATABASE_ACCOUNTS`
* chore(`accounts.sh`): Filepath to local var `DATABASE_VIRTUAL`
* chore(`accounts.sh`): Filepath to local var `DATABASE_DOVECOT_MASTERS`
* chore(`bin/open-dkim`): Filepaths to local vars (accounts,virtual,vhost)
* chore(`relay.sh`): Filepath to local var `DATABASE_SASL_PASSWD`
* chore: Rename method
Prior PR feedback suggested a better helper method name.
* chore: Normalize filtering config lines as input for iterating
* chore: Remove `_is_comment` helper method
No longer serving a purpose with more appropriate filter method for pre-processing the entire config file.
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.

* added new `_log` function
With `_log`, the `_notify` method wa rendered obsolete. `_notify` was
not completely removed due to test failures in `check-for-changes.sh`.
The new `_log` function properly uses log levels such as `trace`,
`debug`, `info`, `warn` and `error`. It provides a cleaner solution
and renders `DMS_DEBUG` obsolete too (as only `_notify` depends on it).
* converted all helper script to new `_log` function
* converted all startup stacks to new `log` function
* `start-mailserver.sh` now uses new `_log` function
* final test and misc small script adjustments
* updated documentation
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/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

`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.
