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.

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 inet:host:port for a TCP socket.
  • Use unix:path 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.
