This helper was to support an earlier ENV for SASL auth support. When extracting logic into individual helpers, it was assumed this was separate from relay support, which it appears was not the case.
---
The `SASL_PASSWD` ENV is specified in tests but no longer used. There is no `external-domain.com` relay configured or tested against anywhere in the project.
The ENV was likely used in tests prior to improved relay support that allowed for adding more than a single set of relay credentials.
---
It likewise has no real relevance anywhere else outside of `relay.sh` as it's the only portion of code to operate with it.
It's only relevant for SASL auth as an SMTP client, not the SMTP server (`smtpd`) SASL support that is delegated to Dovecot. Functionality has been completely migrated into `relay.sh` as a result.
Documentation is poor for this ENV, it is unlikely in wide use? Should consider for removal.
---
The ENV has been dependent upon `RELAY_HOST` to actually enable postfix to use `/etc/postfix/sasl_passwd`, thus not likely relevant in existing setups?
---
Migrate `/etc/postfix/sasl_passwd` check from `tests.bats` as it belongs to relay tests.
* chore: Fix typo
* chore: Apply explicit chroot default for `sender-cleanup`
The implicit default is set to `y` as a compatibility fallback, but otherwise it is [advised to set to `n` going forward](http://www.postfix.org/COMPATIBILITY_README.html#chroot).
Test was changed to catch any backwards-compatibility logs, not just those for `chroot=y`. `using` added as a prefix to avoid catching log message whenever a setting is changed that the default compatibility level is active.
* chore: Set `compatibility_level` in `main.cf`
We retain the level`2` value previously set via scripts. This avoids log noise that isn't helpful.
Applied review feedback to give maintainers some context with this setting and why we have it presently set to `2`.
* fix: Conditionally add service state
These services will no longer copy over state unless they are enabled.
The biggest offender here was ClamAV as it's database that is baked into the docker image is over 200MB and would copy over to every container instance with a volume mounted state directory.
* chore: Add Dovecot to conditional support
* 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
* 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.
* 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 `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

* `update-check.sh` now uses the new log
* refactored `setup-stack.sh`
The changes are:
1. Replaced `""` wiht `''` where possible (reasoning: Bash is very
implicit and I'd like to use `''` where possible to indicate no
variables are expanded here)
2. `> /file` -> `>/file` according to our style guide
3. Some log adjustments for messages where I deemed it appropriate
4. Then, an error message from a Dovecot setup was also prevented (by
adding a check whether the directory is present before a `: >...`
command would create a file in this directory).
These are all small, miscellaneous changes that I wanted to combine into
one commit and ultimately one PR because I see no point in opening a PR
for every small change here. I hope this is fine.
* added a small `sleep` to the `_shutdown` function
This ensure the last log message is actually logged before Supervisor
logs the message that it received a SIGTERM. This makes reading the log
easier because now the causal relationship is shown (we are terminating
Supervisor, and not someone else and we're just logging it).
I forgot to replace `""` with `''` in `update-check.sh`, so I included
it here because this is the last commit before PR review.
* re-add exit on successful update (only)
* re-added date information to update-check log messages
* added `_log_with_date` function
The new function will log a message with a proper timestamp. This is all
handled in `log.sh`, we therefore not need to source other files too.
This will be used in the future by `check-for-changes.sh` as well :)

* 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
The new setup will now set env variables on one place and on one place
only. The old setup used two separate places wich is not DRY and
confusing.
Some default values changed:
1. PFLOGSUMM_TRIGGER: logrotate => none
2. REPORT_SENDER: mailserver-report@HOSTNAME => mailserver-report@DOMAIN
3. REPORT_RECIPIENT: "0" => POSTMASTER_ADDRESS
One env variable was renamed: REPORT_INTERVAL => LOGROTATE_INTERVAL
I believe these defaults to be more sensible, especially the REPORT_RECIPIENT
address. The PFLOGSUMM_TRIGGER value was changed to `none` because otherwise
people would start getting daily Postfix log summary reports automatically.
Now, this is opt-in, and reports are sent only when enabled properly.
Some of the variables changed were marked as deprecated. I removed the note,
as the variables now bear some (sane) defaults again for other variables
(i.e.) REPORT_RECIPIENT is now default for other recipient addresses.

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.

> 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.

Mostly cleans up the code and documents it better, although there are some minor fixes for handling `SSL_DOMAIN` ENV and additional logging added for spotting issues related to it in future when troubleshooting.
Commits are scoped with context messages for easing review if necessary. Overview of changes:
Traefik specific:
- Logic extracted out into it's own function.
- Conditional reworked to assist with debugging.
- `SSL_DOMAIN` must not be empty when attempting to extract.
- Added additional notes.
`SSL_TYPE=letsencrypt` case:
- Revised top note block.
- Correct handling for `SSL_DOMAIN`.
- Removed some unnecessary nesting.
- Less repetitive error message for `LETSENCRYPT_DOMAIN`.
- Added use of panics where appropriate (kept `return 1` so failures still exit functionality early).
- Improved inline docs.
