# SpamAssassin Milter changelog
|
||
|
||
All notable user-facing changes are listed in this changelog.
|
||
|
||
This project follows Rust-flavoured [semantic versioning], with changes to the
|
||
minimum supported Rust version being considered breaking changes.
|
||
|
||
[semantic versioning]: https://doc.rust-lang.org/cargo/reference/semver.html
|
||
|
||
## 0.5.0 (unreleased)
|
||
|
||
The minimum supported Rust version is now 1.65.0.
|
||
|
||
### Changed
|
||
|
||
* The minimum supported Rust version has been raised to 1.65.0.
|
||
|
||
## 0.4.0 (2023-01-29)
|
||
|
||
The minimum supported Rust version is now 1.61.0.
|
||
|
||
### Changed
|
||
|
||
* The minimum supported Rust version has been raised to 1.61.0.
|
||
|
||
### Fixed
|
||
|
||
* The program no longer panics when it cannot write log messages to standard
|
||
error.
|
||
|
||
## 0.3.2 (2022-08-31)
|
||
|
||
### Changed
|
||
|
||
* The command-line user interface has been reimplemented using a lighter-weight,
|
||
no-dependencies approach.
|
||
|
||
While there are some differences in appearance and error reporting, there are
|
||
no functional changes in using the program. Make sure that you are not relying
|
||
on undocumented (and therefore unsupported) behaviour of the old CLI.
|
||
|
||
## 0.3.1 (2022-03-14)
|
||
|
||
### Fixed
|
||
|
||
* The milter’s connection timeout duration has been increased substantially. The
|
||
previously used duration of five minutes turned out to be too short for some
|
||
slow SMTP conversations.
|
||
|
||
## 0.3.0 (2022-03-08)
|
||
|
||
In this release, the milter implementation has been replaced with the new
|
||
[indymilter] library. With this change, there is no longer a dependency on the
|
||
libmilter C library. SpamAssassin Milter is now a pure Rust application.
|
||
|
||
The minimum supported Rust version is now 1.56.1.
|
||
|
||
### Changed
|
||
|
||
* The minimum supported Rust version is now 1.56.1 (using Rust edition 2021).
|
||
* The syntax of the mandatory `SOCKET` argument has changed:
|
||
- Use <code>inet:<em>host</em>:<em>port</em></code> for a TCP socket.
|
||
- Use <code>unix:<em>path</em></code> for a UNIX domain socket.
|
||
* The command-line help information has changed its appearance slightly with the
|
||
update of the underlying [clap] CLI library.
|
||
* The changelog is now maintained in a more structured format, similar to
|
||
https://keepachangelog.com.

|
||
## 0.2.1 (2021-12-23)
|
||
|
||
* Various cosmetic improvements in code and tests, and updates to documentation.
|
||
* Update dependencies.
|
||
|
||
## 0.2.0 (2021-08-26)
|
||
|
||
* Bump minimum supported Rust version to 1.46.0.
|
||
* (defaults change) Invoke `spamc` using the absolute path `/usr/bin/spamc`
|
||
(instead of any executable named `spamc` in the search path). To customise
|
||
this, set the environment variable `SPAMASSASSIN_MILTER_SPAMC` to the desired
|
||
path when building the application.
|
||
* Revise header rewriting logic. Handling and placement of `X-Spam-` headers now
|
||
more accurately mirrors that applied by SpamAssassin.
|
||
* Include authentication status in information passed on to SpamAssassin.
|
||
* Update dependencies.
|
||
|
||
## 0.1.6 (2021-05-17)
|
||
|
||
* Improve processing of incoming `X-Spam-Flag` headers. Previously, in rare
|
||
circumstances a message flagged as spam would not be rejected as requested.
|
||
Reported by Petar Bogdanovic.
|
||
* Update dependencies.
|
||
|
||
## 0.1.5 (2021-03-16)
|
||
|
||
* Read output from `spamc` in a separate thread in order to avoid blocking when
|
||
processing large messages in certain configurations.
|
||
* Document requirement to keep `--max-message-size` setting in sync with
|
||
`spamc`’s `--max-size` setting.
|
||
* Remove overly strict validation of command-line options.
|
||
* Properly specify minimal dependency versions in `Cargo.toml`.
|
||
* Document minimum supported Rust version 1.42.0.
|
||
|
||
## 0.1.4 (2020-10-18)
|
||
|
||
* Correct a typo in log messages.
|
||
* Isolate integration tests from any existing `spamc` configuration present on
|
||
the host.
|
||
* Various à la mode style improvements in code and project metadata.
|
||
|
||
## 0.1.3 (2020-07-04)
|
||
|
||
* Add `--reply-code`, `--reply-status-code`, and `--reply-text` options to allow
|
||
customising the SMTP reply when rejecting spam.
|
||
* Log a warning and do not truncate the message body when `--max-message-size`
|
||
is misconfigured (must be ≥ `spamc` max size as documented).
|
||
* Update dependencies in `Cargo.lock`.
|
||
|
||
## 0.1.2 (2020-06-07)
|
||
|
||
* Bump milter dependency to version 0.2.1.
|
||
* Remove existing UNIX domain socket at target path during startup.
|
||
* Derive `Eq` and `PartialEq` for configuration structs.
|
||
|
||
## 0.1.1 (2020-04-13)
|
||
|
||
* Use `Write::write_all` instead of `Write::write` in `spamc` client, in order
|
||
to ensure buffers are written in their entirety.
|
||
* Do not include `.gitignore` file in published crate.
|
||
|
||
## 0.1.0 (2020-02-23)
|
||
|
||
Initial release.
