Moreover, I added a function to print the whole mail log. Appropriate
comments were added to this function to indicate that one should only
use this function when necessary.
* tests: OAuth2 - Replace Python `/userinfo` endpoint with Caddy
Better documented, easier flow and separation of concerns via Caddy.
The python code had additional noise related to setting up a basic API which is abstracted away via `Caddyfile` config that's dedicated to this task.
* tests: OAuth2 - Minimize noise + Improve test assertion
Caddyfile can use an Access Token instead of a JWT. Much smaller and correct for this OAuth2 configuration. This new value has been documented inline.
Likewise the `sub` field returned is not important to this test. `email_verified` is kept as it may be helpful for further coverage testing.
The actual test-case has better assertions for success and failure by checking for Dovecot logs we expect instead of netcat response.
`oauth2` to `auth` for the Caddy container hostname is not necessary, just a more generic subdomain choice.
* tests: OAuth2 - Caddyfile `imap/xoauth2` route dynamic via query string
This way is more flexible and doesn't require modifying the `Caddyfile` directly, while still easy to use.
Additionally simplifies understanding the Caddyfile to maintainers by removing the `route` directive that was required to ensure a deterministic order of vars.
* tests: OAuth2 - `/imap/xoauth2` respond with IMAP commands for netcat
Since this is the only intended usage, might as well have it respond with the full file content.
* tests: OAuth2 - Implement coverage for `OAUTHBEARER`
Caddyfile route for `/imap/` now accepts any subpath to support handling both `xoauth2` and `oauthbearer` subpaths.
Both SASL mechanisms represent the same information, with `XOAUTH2` being a common mechanism to encounter defined by Google, whilst `OAUTHBEARER` is the newer variant standardized by RFC 7628 but not yet as widely adopted.
The request to `/userinfo` endpoint will be the same, only the `credentials` value to be encoded differs.
Instead of repeating the block for a similar route, this difference is handled via the Caddyfile `map` directive.
We match the path context (_`/xoauth2` or `/oauthbearer`, the `/imap` prefix was stripped by `handle_path` earlier_), when there is a valid match, `sasl_mechanism` and `credentials` map vars are created and assigned to be referenced by the later `respond` directive.
---
Repeat the same test-case logic, DRY with log asserts extracted to a common function call. This should be fine as the auth method will be sufficient to match against or a common failure caught.
* tests: OAuth2 - Minor revisions
Separate test cases and additional comment on creating the same base64 encoded credentials via CLI as an alternative to running Caddy.
Added a simple `compose.yaml` for troubleshooting or running the container for the `/imap/xoauth2` / `/imap/oauthbearer` endpoints.
* tests: OAuth2 - Route endpoints in Caddyfile with snippets instead
`reverse_proxy` was a bit more convenient, but the additional internal ports weren't really relevant. It also added noise to logging when troubleshooting.
The `import` directive with Snippet blocks instead is a bit cleaner, but when used in a single file snippets must be defined prior to referencing them with the `import` directive.
---
`compose.yaml` inlines the examples, with slight modification to `localhost:80`, since the Caddyfile examples `auth.example.test` is more relevant to the tests which can use it, and not applicable to troubleshooting locally outside of tests.
* chore: Add entry to `CHANGELOG.md`
* chore: Additional context on access token
I figured this was a useful comment to reference related to the setting if it's ever being changed or needs to be better understood (linked issue is a common failure that can be encountered related to this restriction).
This is a more explicit reminder for any future contributors that get thrown off by the usage of `sed` here and may be inclined to change it.
Add a link to reference a comment where it's already been explored what the alternative `sed` invocations available are.
The new function, called `_send_email_with_mid`, aligns with suggestions
from @polarethene and is heavily simplified compared to its predecessor
`_send_email_and_get_id`. New helpers will be introduced to filter logs
according to the MID constructed in this function.
* correct misc typos
We also seem to be favoring `behavior` over `behaviour`.
* bump MkDocs version
* resolve errors shown when buildg docs
* improve the Rspamd page
* behaviour -> behavior
Streamline the usage of this word. The majority used behavior, so I
opted to go with this way of spelling it.
* Apply suggestions from code review

docs: Rspamd DKIM config (`dkim_signing.conf`) example has been simplified via `path` + `selector` settings.

In Docker Compose `.env` files are parsed properly when values are wrapped with quotes. Trailing white-space is also discarded, like it would be with shell variables.
This is not the case with `docker run` or other CRI like `podman` (_including it's compose equivalent support_). Those will parse the quotes to be included in a literal string value. Trailing white-space is also retained.
Hence a default with a trailing space is not compatible across CRI. This change documents the default with additional context on how to include a trailing white-space with a custom value for the users CRI choice. It additionally clearly communicates the opt-out value for this feature.
* feat: add support for MTA-STS for outgoing mails
* Hook-up mta-sts-daemon into basic process handling test
* fix: Call python script directly
The python3 shebang will run it, which will now meet the expectations of the process testing via pgrep. fail2ban has the same approach.

* ci: `.gitattributes` - Ensure `eol=lf` for shell scripts
- These files should always use LF for line endings during a checkout.
- `Dockerfile` does not like building with HereDoc `RUN` scripts that expect LF.
* 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.
* fix: `supervisor-app.conf` - Correct `postgrey` log location
Looks like this should have been like every other service and reference a log file(s) based on program name in the supervisor log directory.
* tests: Adjust log location for `postgrey_enabled.bats`
* docs: Debugging - Delivery failure from service downtime
Services may be temporarily down, such as when restarted when certificates are updated due to the `check-for-changes.sh` service. This is another known source of intermittent delivery failures.
