The mailserver suite with the 'moo' – 🐮 + 🐋 = 💕

Dear mailcow Community,

2024 is coming to an end, and we, too, are heading into a well-deserved winter break.

2024-11b Update (Released on November 15, 2024)

Fixes

• mysql: For new mailcow installations using the latest MariaDB 10.5 (default), a low thread_stack value prevented the mailcow database from being created. The value has been increased to 192k (previously 128k).
  ➡️ PR #6172

2024-08a (Released on 20th August 2024)

Dovecot updated to 2.3.21.1

Other Changes

• Fixed issues with parsing the Docker version number in the generate-config.sh and update.sh scripts.
• Some Dockerfiles were refactored (this has no impact on operations, it only serves for future development).
• An exit condition was added to Dovecot concerning the download of sa-rules. Previously, the download had to be successful; otherwise, Dovecot would not start. Now, if the download fails after several attempts, Dovecot will still start.
• In Docker containers that used the mysqladmin tool, the tool has been replaced with the newer mariadb-admin with the same functionality to prevent future compatibility issues.
• Several Bash variables in the scripts are now handled correctly (quoting), and some strange non-UTF-8 characters have been replaced.
• Due to the Rspamd update to 3.9.1, UTF-8 decoding in the Pushover and quarantine systems was broken, which could have led to unexpected results when emojis were in the header. This has been fixed.

2024-08 (Released on 15th August 2024)

Moohoo everyone!

August is here, and mailcow brings you a major update for this (hopefully not too hot) month.

This time, we have some significant changes on board that we would like to introduce to you:

2024-07 (Release on 5th August 2024)

Moohoo everyone!

2024-06c (Release on 12th July 2024)

• After some back and forth (sorry about that…), we have decided to keep the affected PHP container on a working version (yes, there was one :D) until we can confirm through deeper tests that it finally works with a patched Alpine… until then, the container will remain “frozen.” The new container caused Roundcube users to experience issues, mainly due to permissions. Since we cannot rule out that this might break more third-party apps, we have reverted the version.
• We fixed an error in the UI where the version modal was not opening correctly. Although it did open, it redirected you to the release page directly, making the modal unnecessary…

2024-06b (Release on 12th July 2024)

• Improved regular expression in the backup/restore script, it should now support numbers like 10, 20, etc.
• The PHP container has been built based on Debian 12. This should (please… the bug is really annoying…) finally fix the issues some of you had regarding blank mailcow UI or incorrect container values within the UI (etc.). We are still working on identifying the problem in the Alpine container so that we can use the Alpine base again in the long term (due to the smaller container size).
• The WIP warning for ARM64 versions has been removed from the web UI. It is now (actually from the beginning…) stable! Thanks to everyone using it!
• Postfix’s Postscreen access list has been updated as of July 1, 2024.

2024-06a (Release on 27th June 2024)

• Rolledback broken Translation links
• Fixed broken Curl Request at some Hosts inside PHP-FPM Container due to c-ares change

2024-06 (Release on 27th June 2024)

Moohoo everyone!

After our statement, it’s time to bring you an update again.

This time with some additional information:

⚠️ Critical Changes

Postfix TLS 1.1, TLS 1.0 Discontinuation

As part of the 2024-06 update, Postfix was updated to 3.7.10 and Debian 12. At the same time, this update requires communication between SMTP servers to use at least TLS version 1.2. This means we are discontinuing support for the older TLS versions 1.0 and 1.1.

Dear mailcow Community,

mailcow continues to enjoy increasing popularity, and we are, of course, delighted by this.

To continue delivering the necessary quality in the project and always meet the community’s expectations, we have adjusted and extended our update intervals accordingly. This allows us to maintain the high quality of updates for bug and feature requests.

Going forward, we will tie the update intervals to the significance of the scope of the requests. Security fixes will remain an exception and will continue to be released as quickly as possible to ensure the security and stability of your installations.

2024-04 (Release April 4th, 2024)

Moohoo Everyone!

Moohoo everyone!

As already announced on social media channels, today we are serving you a new edition of our section: What's up?.

Today, we are explicitly discussing a topic of burning interest to all of us: LDAP/OIDC Integration and the associated overhaul of the authentication system.

We have kept you updated in the past that we are feverishly working on integrating LDAP and OIDC. After all, this function is not without reason one of the most requested features for mailcow ever – and rightly so!

However, our plan was to release this whole thing in the first quarter of 2024 or maybe even around Christmas 2023. As you have noticed, both timelines could not be met…

2024-02 (Release 15th February 2024)

Moohoo Everyone!

2024-01e (Release: 08th Februars 2024)

Netfilter Enhancements
