For an upcoming PR, these changes are required, because the script that
is using the helpers uses `set -eE`. This leads to situations where
errors are not properly handled in our helpers (yet; I plan on changing
that in the future).
* move modules adjustment file to new location
Because we link `/tmp/docker-mailserver/rspamd/override.d` to
`/etc/rspamd/override.d`, I think it makes sense to move the modules
adjustment file into `/tmp/docker-mailserver/rspamd/` as well.
I write the code in a way that it is backwards compatible for now, so
this is NOT a breaking change.
* minor improvement to `__rspamd__handle_user_modules_adjustments`
The expansion of `ARGUMENT3` is now done in a way that only adds the
whitespace in case the variable is set and not null.
* move test file structure to respect latest changes
Because we're now linking `rspamd/override.d/`, we can simplify the
setup a bit. But this requires a change in directory structure.
The current Rspamd test will be renamed to `rspamd_full.bats`, because I
plan on adding more tests in different files for different feature sets.
This is done to make this feature well-tested!
* improved and added tests to Rspamd-full
FYI: The line
```bats
_run_in_container grep 'sieve_global_extensions.*\+vnd\.dovecot\.pipe'
"${SIEVE_CONFIG_FILE}"
```
was testing a condition that should actually not be met, but when I
started working on this feature, I thought this was the correct
configuration. Adding the `assert_success` statements revealed this
wrong line.
I also added tests to check whether `override.d` is linked correctly.
* renamed: `rspamd.bats` => `rspamd_full.bats`
* added new tests for incomplete Rspamd feature set
We now test that warnings are emitted & features are disabled correctly.
* update documentation
* added checks whether OpenDKIM/OpenDMARC/policyd-spf are enabled
* added functions to check if VAR is 0/0 or an int
and also added tests.
I also adjusted the test file to not run in a container, because there
is no need. This also decreases test time, which, in turn, increases
maintainers' happiness.
* added more checks to Rspamd setup
I added the helpers from the previous commit to the Rspamd setup to make
the whole setup more robust, and indicate to the user that an ENV
variable's value is incorrect.
While we did not issues for this in the past, I believe it to be
worthwhile for the future.
* added canonical directory for users to place files in
This dir is canonical with DMS's optional configuration dirs, as it
lives in well-known volume mounts. Hence, users will not need to adjust
`/etc/rspamd/override.d` manually anymore, or mount a volume to this
place.
The docs explain this now, but the DKIM page needs a slight update on
this too I guess. I will follow-up here.
* misc minor improvements
* use variables for common directories
* fixed special bits for maildrop and public dir
After changing the group, special bits are lost, but they should be set for the directories `/var/spool/postfix/{maildrop,public}`, otherwise you see the following error:
```
postfix/postdrop[17400]: warning: mail_queue_enter: create file maildrop/729504.17400: Permission denied
```
* fix: Match octal permissions originally provided
Officially Postfix source seems to imply:
- `730` for `maildrop/` (_but has mentioned a sticky bit in the past, set-gid bit only for the postdrop binary involved_)
- `710` for `public/`
Both folders are assigned the same group that `postdrop` belongs to which has the SGID permission for it's executable. SGID special bit on`public/` doesn't seem necessary, but left as-is to match the default from Debian.

* remove PostSRSD wrapper
The setup is now completely done during _actual_ setup phase. The
wrapper did not even catch signals (SIGINT, etc.), which I think is
strange.
I also added all the ENVs the wrapper relied on (which previously could
have been unset) to the variables script.
* forgot adjusting the `Dockerfile`
* chore: Only replace `CHKSUM_FILE` when a change has been processed
* chore: Change Detection service should be the last daemon started
* chore: Remove 10 second startup delay for change detector
There should be no concern with conflicts as any writes should have already been done by the time this daemon service is started.
* tests(fix): `smtp_delivery.bats` must wait for Amavis
The change event for adding a user can be processed much sooner now, which means Amavis may not yet be ready.
Added extra condition to wait on at least the Amavis port being reachable, and some failure asserts with the mail queue to better catch / debug when this problem occurs.
* chore: Add some minor delay to avoid Amavis failing to connect
* tests(refactor): Make test cases for opendkim keysizes DRY
- These all do roughly the same logic that can be split into two separate methods.
- `_should_generate_dkim_key()` covers a bit more logic as it can be leveraged to handle other test cases that also perform the same logic.
- The `config/opendkim/` doesn't seem necessary for tests. Only the first few test cases here are testing against it, so we can conditionally make that available. `process_check_restart.bats` also depended on it to run OpenDKIM successfully, but this was due to the `setup-stack.sh` config defaults failing to find an "empty" file forcing `supervisord` to constantly restart the process..
- With this, there we inverse the default opendkim config, so we don't have to mount unique / empty subfolders for each test case, followed by copying over the two extra configs.
* tests(refactor): DRY up more test cases
All the remaining test cases but the last one were refactored here for a clean commit diff. The last test case will be refactored in the following commit.
Plenty of repeated logic spread across these test cases, now condensed into shared methods.
* tests(refactor): Make final test case DRY
* chore: Migrate to new testing helpers
* chore: Revise test case descriptions
* tests(refactor): Improve and simplify assertions
* tests(refactor): Use common container setup instead of `docker run`
- As the majority of test cases are only running `open-dkim` helper, we don't actually have to wait for a full container setup. So an alternative container start is called.
- Also improves assertions a bit more instead of just counting lines.
- Some test cases don't bind mount all of `/tmp/docker-mailserver` contents, thus don't raise permission errors on subsequent test runs.
- Instead of `rm -f` on some config files, have opted to mount them read-only instead, or alternatively mount an anonymous empty volume instead.
- Collapsed the first three test cases into one, thus no `setup_file()` necessary.
- Shift the `_wait_for_finished_setup_in_container()` method into `_common_container_setup()` instead since nothing else is using `_common_container_start()` yet, this allows for avoiding the wait.
* tests(refactor): Collapse dkim key size test cases into single test case
This makes these tests a bit more DRY, and enhances the raised quality issue with these tests. Now not only is the domain checked in the generated DNS dkim record, but we also verify the key size is corrected in the public and private keys via openssl.
* chore: Revise container names
* chore: Swap order of test case 1 and 2
* tests(refactor): Assert generated log output
- `__should_have_tables_trustedhosts_for_domain` shifted in each test case to just after generating the domains keys.
- Asserts `open-dkim` logs instead of just counting them.
- Added checks for domains that should not be present in a test case.
- Additional coverage and notes about the alias from vhost `@localdomain.com`
- Single assert statement with switch statement as all are using common args.
* chore: Minor changes
* tests(refactor): Share `find` logic in helpers and tests
* tests(fix): Listing file content does not need to match line order
The order printed from local system vs CI differed causing the CI to fail. The order of lines is irrelevant so `--index` is not required.
Additionally correct the prefix of the called method to be only one `_` now that it's a `common.bash` helper method.
* chore: Collapse custom DKIM selector test into custom DKIM domain test
These cover the same test logic for the most part, the first domain could also be testing the custom selector.
`special_use_folders.bats` + `mailbox_format_dbox` can assert lines instead, removing the need for `--partial`.

* chore: Split switch statement method into wrapper methods

* only add Amavis configuration to Postfix when enabled
Since I am running Rspamd nowadays, I noticed there still are ports open
that belong to Amavis. This is because the Amavis configuration is a
fixed part of Postfix's `master.cf`. I changed that. Now, the Amavis
section is added when Amavis really is enabled.
I took the chance and added proper indentation to `master.cf`; hence the
diff is a bit fuzzy. **But**, only the Amavis part was adjusted, the
rest is just styling.
This appears to have been added to replace the `fam` package in an early version of DMS with Courier for IMAP instead of Dovecot on an Ubuntu 14.04 base image.
It does not appear to serve a purpose anymore.
* chore: Remove the wrapper script for `fail2ban`
- This does not appear necessary. The server can be run with foreground mode.
- `daemons-stack.sh` removal of the socket can be handled by the fail2ban server when using the `-x` option.
* chore: Remove `touch /var/log/auth.log`
These were both added as supposed fixes in 2016 for the then Ubuntu 2014 base image.
Removing them causes no failures in tests.
* fix: Install optional python packages for `fail2ban`
These have barely any overhead in layer weight. The DNS package may provide some QoL improvements, while the `pyinotify` is a better alternative than polling logs to check for updates.
We have `gamin` package installed but `fail2ban` would complain in the log that it was not able to initialize the module for it. There only appears to be a `python-gamin` dependent on EOL python 2, no longer available from Debian Bullseye.
* added options to toggle OpenDKIM & OpenDMARC
rspamd can provide DKIM signing and DMARC checking itself, so users
should be able to disable OpenDKIM & OpenDMARC. The default is left at
1, so users have to to opt-in when the want to disable the features.
* misc small enhancements
* adjusted start of rspamd
The order of starting redis + rspamd was reversed (now correct) and
rspamd now starts with the correct user.
* adjusted rspamd core configuration
The main configuration was revised. This includes AV configuration as
well as worker/proxy/controller configuration used to control the main
rspamd processes.
The configuration is not tested extensively, but well enough that I am
confident to go forward with it until we declare rspamd support as
stable.
* update & improve the documentation
* add tests
These are some initial tests which test the most basic functionality.
* tests(refactor): Improve consistency and documentation for test helpers (#3012)
* added `ALWAYS_RUN` target `Makefile` recipies (#3013)
This ensures the recipies are always run.

* fix: RSPAM ENV should only add to array if ENV enabled
* fix: Correctly match ownership for Postfix content
- `/var/lib/postfix` dir and content is `postfix:postfix`, not `postfix:root`.
- `/var/spool/postfix` is `root:root` not `postfix:root` like it's content.
- Add additional comments, including ownership changes by Postfix to `/var/spool/postfix` when process starts / restarts.
* fix: Ensure correct `chown -R` user and groups applied
These were all fine except for clamav not using the correct clamav group. `fetchmail` group is `nogroup` as per the group set by the debian package.
Additionally formatted the `-eq 1 ]]` content to align on the same columns, and added additional comment about the purpose of this `chown -R` usage so that it's clear what bug / breakage it's attempting to prevent / fix.
* refactor: `misc-stack.sh` conditional handling
The last condition doesn't get triggered at all AFAIK. Nor does it make sense to make a folder path with `mkdir -p` to symlink to when the container does not have anything to copy over?
- If that was for files, the `mkdir -p` approach seems invalid?
- If it was for a directory that could come up later, it should instead be created in advance? None of the current values for `FILES` seem to hit this path.
Removing as it doesn't seem relevant to current support.
Symlinking was done for each case, I've opted to just perform that after the conditional instead.
Additional inline docs added for additional context.
* chore: Move amavis `chown -R` fix into `misc-stack.sh`
This was handled separately for some reason. It belongs with the other services handling this fix in `misc-stack.sh`.
The `-h` option isn't relevant, when paired with `-R` it has no effect.
* fix: Dockerfile should preserve `clamav` ownership with `COPY --link`
The UID and GID were copied over but would not match `clamav` user and group due to numeric ID mismatch between containers. `--chown=clamav` fixes that.
* chore: Workaround `buildx` bug with separate `chown -R`
Avoids increasing the image weight from this change by leveraging `COPY` in the final stage.
* chore: `COPY --link` from a separate stage instead of relying on scratch
The `scratch` approach wasn't great. A single layer invalidation in the previous stage would result in a new 600MB layer to store.
`make build` with this change seems to barely be affected by such if a change came before copying over the linked stage, although with `buildx` and the `docker-container` driver with `--load` it would take much longer to import and seemed to keep adding storage. Possibly because I was testing with a minimal `buildx` command, that wasn't leveraging proper cache options?
* lint: Appease the linting gods
* chore: Align `misc-stack.sh` paths for `chown -R` operations
Review feedback
Co-authored-by: Casper <casperklein@users.noreply.github.com>
* fix: Reduce one extra cache layer copy
No apparent advantage of a `COPY --link` initially in separate stage.
Just `COPY --chown` in the separate stage and `COPY --link` the stage content. 230MB less in build cache used.
* fix: Remove separate ClamAV stage by adding `clamav` user explicitly
Creating the user before the package is installed allows to ensure a fixed numeric ID that we can provide to `--chown` that is compatible with `--link`.
This keeps the build cache minimal for CI, without being anymore complex as a workaround than the separate stage was for the most part.
* chore: Add reference link regarding users to `misc-stack.sh`
* tests(refactor): `mail_changedetector.bats` - Leverage DRY methods
`supervisorctl tail` is not the most reliably way to get logs for the latest change detection and has been known to be fragile in the past.
We can instead read the full log for the service directly with `tac` and `sed` to extract all log content since the last change detection.
Common asserts have also been extracted out into separate methods.
* tests(chore): Remove sleep and redundant change event
Container 1 is still blocked at this point from an existing lock and change event.
Make the lock stale immediately and no extra sleep is required when paired with the helper method to wait until the event is processed (which should remove the stale lock).
* tests(refactor): Add more DRY methods
- Simplify the test case so it's easier to grok.
- 2nd test case (blocking) extracts out initial setup into a separate method and merges the later service restart logic which is redundant.
- Additional comments for improved context of what is going on / expected.
* tests(chore): Revise the change detection helper method
- Add explicit counting arg to change detection support.
- Extract revised logic into it's own generic helper method.
- Utilize this for a separate method that monitors for a change event having started, but not waiting for completion.
This allows dropping the 40 sec of remaining `sleep` in `mail_changedetector` test. It was also required due to potentially missing the timing of a change event completing concurrently in a 2nd container that needed to be waited on and then checked.
* tests(chore): Migrate to current test conventions
- Switch to common container setup helpers
- Update container name and change usage to variables instead.
- Adopt the new convention of prefix variable for test cases (revised test case descriptions).
* tests(chore): Remove legacy change detection
This has since been replaced with the new helper watches the `changedetector` service logs directly instead of only detecting a change has occurred via checksum comparison.
No tests use this method anymore, it was originally for `tests.bats`. Thus the tests in `test_helper.bats` are being dropped too. The new helper has test coverage in `changedetector` tests.
* chore: Lock removal should not incur `sleep 5` afterwards
- A new lock should be created by this script after removal. The sleep doesn't help avoid a race condition with lock file creation after removal.
- Reduces test time as a bonus.
- Added some additional comments to test.
* tests(chore): `tls_letsencrypt.bats` leverage improved change detection
- No need to wait on the change detection service anymore during container startup.
- No need to count change events processed either as waiting a fixed duration is no longer relied on.
- This makes the reload count method redundant, dropped.
* tests(chore): Convert `setup-cli.bats` to new test conventions
This test file was already adapted to the original common setup helpers.
- `TEST_NAME` replaced with `CONTAINER_NAME`.
- Prefix var added, test case descriptions drop explicit prefix.
- No other changes.
* tests(chore): Extract out helpers related to change-detection
- New helper file for sharing these helpers to tests.
- Includes the helpful log method from changedetector tests.
- No longer need to maintain duplicate copies of these methods during the test migration. All tests that use them are now importing the separate helper file.
- `tls_letsencrypt.bats` has switched to using the log helper.
- Generic log count helper is removed from `test_helper/common.bash` as any test that needs it in future can adapt to `helper/common.bash`.
* tests(refactor): `tls_letsencrypt.bats` remove `_get_service_logs()`
This helper does not seem useful as moving away from `supervisorctl tail` and no other tests had a need for it.
* tests(chore): Remove common setup methods from `test_helper/common.bash`
No other tests depend on this. Future tests will adopt the revised versions from `helper/setup.bash`.
Additionally updates `helper/setup.bash` comments that are no longer applicable to `TEST_TMP_CONFIG` and `CONTAINER_NAME`.
* chore: Use `|| true` to simplify setting `EXPECTED_COUNT` correctly
* chore: Drop ENV `ENABLE_POSTFIX_VIRTUAL_TRANSPORT`
* tests(chore): Remove redundant `dovecot-lmtp` config
None of this is needed. Only relevant change is changing the LMTP service listener for Dovecot and that can be delegated to `user-patches.sh`.
* tests(refactor): Use `user-patches.sh` instead of replacing config file
The only relevant changes in `test/config/dovecot-lmtp` regarding LMTP was:
- `/etc/dovecot/dovecot.conf` (`protocols = imap lmtp`) and `/etc/dovecot/protocols.d/` (`protocols = $protocols lmtp`).
- `conf.d/10-master.conf` only changed the LMTP service listener from a unix socket to TCP on port 24 (_this was the only change required for the test to pass_).
None of those configs are required as:
- `protocols = imap pop3 lmtp` [is the upstream default](https://doc.dovecot.org/settings/core/#core_setting-protocols), no need to add `lmtp`.
- The LMTP service listener is now configured for the test with `user-patches.sh`.
* tests(refactor): `mail_lmtp_ip.bats`
- Converted to new testing conventions and common container helpers.
- `ENABLE_POSTFIX_VIRTUAL_TRANSPORT` was not relevant, dropped.
- Revised test cases, logic remains the same.
- Large custom config used was not documented and doesn't appear to serve any purpose. Simplified by replacing with a single modification with `user-patches.sh`.
- Added some additional comments for context of test and improvements that could be made.
* tests(chore): Adjust comments
The comment from `mail_hostname` provides no valid context, it was likely copied over from `tests.bats` in Oct 2020 by accident.
The email sent is just for testing, nothing relevant to LMTP.
---
Added additional comment for test to reference extra information from.
* tests(chore): Update similar log line matching
Extracts out the match pattern and formatting commands into separate vars (reduces horizontal scrolling), and includes extra docs about what the matched line should be expected to look like.
* fix: Workaround `postconf` write settle logic
After updating `main.cf`, to avoid an enforced delay from reading the config by postfix tools, we can ensure the modified time is at least 2 seconds in the past as a workaround. This should be ok with our usage AFAIK.
Shaves off 2+ seconds roughly off each container startup, reduces roughly 2+ minutes off tests.
* chore: Only modify `mtime` if less than 2 seconds ago
- Slight improvement by avoiding unnecessary writes with a conditional check on the util method.
- Can more comfortably call this during `postfix reload` in the change detection cycle now.
- Identified other tests that'd benefit from this, created a helper method to call instead of copy/paste.
- The `setup email restrict` command also did a modification and reload. Added util method here too.
* tests(fix): `mail_smtponly.bats` should wait for Postfix
- `postfix reload` fails if the service is not ready yet.
- `service postfix reload` and `/etc/init.d/postfix reload` presumably wait until it is ready? (as these work regardless)
* chore: Review feedback - Move reload method into utilities
* chore: Set `TLS_INTERMEDIATE_SUITE` to only use TLS 1.2 ciphersuites
Removes support of the following cipher suites that are only valid for TLS 1.0 + 1.1:
- `ECDHE-ECDSA-AES128-SHA`
- `ECDHE-RSA-AES128-SHA`
- `ECDHE-ECDSA-AES256-SHA`
- `ECDHE-RSA-AES256-SHA`
- `DHE-RSA-AES128-SHA`
- `DHE-RSA-AES256-SHA`
* chore: Update TLS version min and ignore settings
These are now the same as modern settings.
* fix: Remove min TLS support workaround
No longer required now that outdated TLS versions have been dropped.
* tests: Remove support for TLS 1.0 and 1.1 ciphersuites
* tests: Remove support for TLS 1.0 and 1.1 ciphersuites (Port 25)
The removed SHA1 cipher suites are still supported in TLS 1.2, thus they've been excluded for port 25 via the `SHA1` exclusion pattern in `main.cf`.
With `reload` a change detection event during local testing can be processed in less than a second according to logs. Previously this was 5+ seconds (_plus additional downtime for Postfix/Dovecot to become available again_).
In the past it was apparently an issue to use `<service> reload` due to a concern with the PID for wrapper scripts that `supervisorctl` managed, thus `supervisorctl <service> restart` had been used. Past discussions with maintainers suggest this is not likely an issue anymore, and `reload` should be fine to switch to now 👍
---
**NOTE:** It may not be an issue in the CI, but on _**local systems running tests may risk failure in `setup-cli.bats` from a false positive**_ due to 1 second polling window of the test helper method, and a change event being possible to occur entirely between the two checks undetected by the current approach.
If this is a problem, we may need to think of a better way to catch the change. The `letsencrypt` test counts how many change events are expected to have been processed, and this could technically be leveraged by the test helper too.
---
**NOTE:** These two lines (_with regex pattern for postfix_) are output in the terminal when using the services respective `reload` commands:
```
postfix/master.*: reload -- version .*, configuration /etc/postfix
dovecot: master: Warning: SIGHUP received - reloading configuration
```
I wasn't sure how to match them as they did not appear in the `changedetector` log (_**EDIT:** they appear in the main log output, eg `docker logs <container name>`_).
Instead I've just monitored the `changedetector` log messages, which should be ok for logic that previously needed to ensure Dovecot / Postfix was back up after the `restart` was issued.
---
Commit history:
* chore: Change events `reload` Dovecot and Postfix instead of `restart`
Reloading is faster than restarting the processes.
Restarting is a bit heavy handed here and may no longer be necessary for general usage?
* tests: Adapt tests to support service `reload` instead of `restart`
* chore: Additional logging for debugging change event logs
* fix: Wait on change detection, then verify directory created
Change detection is too fast now (0-1 seconds vs 5+).
Directory being waited on here was created near the end of a change event, reducing that time to detect a change by the utility method further.
We can instead check that the directory exists after the change detection event is completed.
* chore: Keep using the maildir polling check
We don't presently use remote storage in tests, but it might be relevant in future when testing NFS.
This at least avoids any confusing failure happening when that scenario is tested.
As per deprecation notice from v11.3 release notes, and a related prior PR; this ENV is to be removed.
It's no longer considered useful, and none of the tests that configured it were actually using it for relaying anything.
This new script is a clean way of handling the installation of packages.
I think the huge `RUN` command in `Dockerfile` was hard to read and
maintain.
Using a script is a non-issue, as the image is rebuilt whenever the
script is touched.

This PR prepares for other PRs that use the newly introduced helper
functions. The `_log` function itself was adjusted a bit to be shorter
and more concise.
* 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.

When waiting on an account to be added to `postfix-accounts.cf`, Dovecot account creation during the startup process had already run.
Startup continued without properly creating the mail account for Dovecot. Methods like `setup email list` (with `ENABLE_QUOTAS=1`) would fail. `changedetector` service was required to be triggered to re-create Dovecot users.
- Wrapped the logic for wait + shutdown into a function call.
- Moved `_create_accounts()` to bottom of the setup function.
See the associated PR for more detailed commentary on specific changes.
### Commands refactored:
- User (**All:** add / list / update / del + _dovecot-master variants_)
- Quota (**All:** set / del)
- Virtual Alias (**All:** add / list /del)
- Relay (**All:** add-relayhost / add-sasl / exclude-domain)
### Overall changes involve:
- **Fairly common structure:**
- `_main` method at the top provides an overview of logical steps:
- After all methods are declared beneath it (_and imported from the new `helpers/database/db.sh`_), the `_main` is called at the bottom of the file.
- `delmailuser` additionally processes option support for `-y` prior to calling `_main`.
- `__usage` is now consistent with each of these commands, along with the `help` command.
- Most logic delegated to new helper scripts. Some duplicate content remains on the basis that it's low-risk to maintenance and avoids less hassle to jump between files to check a single line, usually this is arg validation.
- Error handling should be more consistent, along with var names (_no more `USER`/`EMAIL`/`FULL_EMAIL` to refer to the same expected value_).
- **Three new management scripts** (in `helpers/database/manage/`) using a common structure for managing changes to their respective "Database" config file.
- `postfix-accounts.sh` unified not only add and update commands, but also all the dovecot-master versions, a single password call for all 4 of them, with a 5th consumer of the password prompt from the relay command `addsaslpassword`.
- These scripts delegate actual writes to `helpers/database/db.sh` which provides a common API to support the changes made.
- This is more verbose/complex vs the current inline operations each command currently has, as it provides generic support instead of slightly different variations being maintained, along with handling some edge cases that existed and would lead to bugs (notably substring matches).
- Centralizing changes here seems wiser than scattered about. I've tried to make it easy to grok, hopefully it's not worse than the current situation.
- List operations were kept in their respective commands, `db.sh` is only really managing writes. I didn't see a nice way for removing the code duplication for list commands as the duplication was fairly minimal, especially for `listalias` and `listdovecotmasteruser` which were quite simple in their differences in the loop body.
- `listmailuser` and `delmailuser` also retain methods exclusive to respective commands, I wasn't sure if there was any benefit to move those, but they were refactored.
* fix: Reload `amavisd-new` when vhost config is updated
Amavis was not aware of new domains in `/etc/postfix/vhost` as it did not refresh it's sources upon change detection.
- Inline docs for `check-for-changes.sh` have been shuffled around and revised a bit.
- Change processing extracted from the main change detection loop method to their own methods:
- `_get_changed_files()` - Clarifies what is going on (and how) without having to look it up. To reduce noise in the main logic loop, extracted to a separate method.
- `_postfix_dovecot_changes()` - The bulk of change processing was moved to this method. I've added conditionals to only run relevant logic.
- `_ssl_changes()` - Just shifted, no logic changed. `REGEX_NEVER_MATCH` and `ACME_CERT_DIR` vars scope set to `local`.
* 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: 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(`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.
