`stderr` is filtered by `grep` to discard unwanted (expected) log noise when appending the override `postfix-main.cf` content (_updated settings did not replace earlier defined instances_).
That `grep` filter introduced a regression into DMS v14 release, since any other `stderr` content not being excluded was now blended into `stdout` and redirected with the original `stdout` output for the `postconf -n` command.
The fix is to ensure the `grep` output is redirect to `stderr` to avoid that mishap.
Custom parameters must be referenced to be retained when `postconf -n` is run. If those parameters are referenced by `postfix-master.cf` this needs to update `master.cf` before updating `main.cf`.
* 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

* chore: Disable `smtputf8` support in config
This was always configured disabled at runtime, better to just set explicitly in `main.cf` unless config diverges when Dovecot is enabled to opt-out of this feature.
* 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`
