-When a problem occurs, then always for a reason! What you want to do in such a case is:
+# Contribution Guidelines
+**_Last modified on 12th November 2025_**
 
+First of all, thank you for wanting to provide a bugfix or a new feature for the mailcow community, it's because of your help that the project can continue to grow!
+
+As we want to keep mailcow's development structured we setup these Guidelines which helps you to create your issue/pull request accordingly.
+
+**PLEASE NOTE, THAT WE WILL CLOSE ISSUES/PULL REQUESTS IF THEY DON'T FULFILL OUR WRITTEN GUIDELINES WRITTEN INSIDE THIS DOCUMENT**. So please check this guidelines before you propose a Issue/Pull Request.
+
+## Topics

+
+## Pull Requests
+**_Last modified on 15th August 2024_**
+
+However, please note the following regarding pull requests:
+
+1. **ALWAYS** create your PR using the staging branch of your locally cloned mailcow instance, as the pull request will end up in said staging branch of mailcow once approved. Ideally, you should simply create a new branch for your pull request that is named after the type of your PR (e.g. `feat/` for function updates or `fix/` for bug fixes) and the actual content (e.g. `sogo-6.0.0` for an update from SOGo to version 6 or `html-escape` for a fix that includes escaping HTML in mailcow).
+2. **ALWAYS** report/request issues/features in the english language, even though mailcow is a german based company. This is done to allow other GitHub users to reply to your issues/requests too which did not speak german or other languages besides english.
+3. Please **keep** this pull request branch **clean** and free of commits that have nothing to do with the changes you have made (e.g. commits from other users from other branches). *If you make changes to the `update.sh` script or other scripts that trigger a commit, there is usually a developer mode for clean working in this case.*
+4. **Test your changes before you commit them as a pull request.** <ins>If possible</ins>, write a small **test log** or demonstrate the functionality with a **screenshot or GIF**. *We will of course also test your pull request ourselves, but proof from you will save us the question of whether you have tested your own changes yourself.*
+5. **Please use** the pull request template we provide once creating a pull request. *HINT: During editing you encounter comments which looks like: `<!-- CONTENT -->`. These can be removed or kept, as they will not rendered later on GitHub! Please only create actual content without the said comments.* 
+6. Please **ALWAYS** create the actual pull request against the staging branch and **NEVER** directly against the master branch. *If you forget to do this, our moobot will remind you to switch the branch to staging.*
+7. Wait for a merge commit: It may happen that we do not accept your pull request immediately or sometimes not at all for various reasons. Please do not be disappointed if this is the case. We always endeavor to incorporate any meaningful changes from the community into the mailcow project.
+8. If you are planning larger and therefore more complex pull requests, it would be advisable to first announce this in a separate issue and then start implementing it after the idea has been accepted in order to avoid unnecessary frustration and effort!
+9. If your PR requires a Docker image rebuild (changes to Dockerfiles or files in data/Dockerfiles/), update the image tag in docker-compose.yml. Use the base-image versioning (e.g. ghcr.io/mailcow/sogo:5.12.4 → :5.12.5 for version bumps; append a letter for patch fixes, e.g. :5.12.4a). Follow this scheme.

+
+## Issue Reporting
+**_Last modified on 12th November 2025_**
+
+If you plan to report a issue within mailcow please read and understand the following rules:
+
+### Security disclosures / Security-related fixes
+- Security vulnerabilities and security fixes must always be reported confidentially first to the contact address specified in SECURITY.md before they are integrated, published, or publicly disclosed in issues/PRs. Please wait for a response from the specified contact to ensure coordinated and responsible disclosure.
+
+### Issue Reporting Guidelines
+
+1. **ONLY** use the issue tracker for bug reports or improvement requests and NOT for support questions. For support questions you can either contact the [mailcow community on Telegram](https://docs.mailcow.email/#community-support-and-chat) or the mailcow team directly in exchange for a [support fee](https://docs.mailcow.email/#commercial-support).
+2. **ONLY** report an error if you have the **necessary know-how (at least the basics)** for the administration of an e-mail server and the usage of Docker. mailcow is a complex and fully-fledged e-mail server including groupware components on a Docker basement and it requires a bit of technical know-how for debugging and operating.
+3. **ALWAYS** report/request issues/features in the english language, even though mailcow is a german based company. This is done to allow other GitHub users to reply to your issues/requests too which did not speak german or other languages besides english.
+4. **ONLY** report bugs that are contained in the latest mailcow release series. *The definition of the latest release series includes the last major patch (e.g. 2023-12) and all minor patches (revisions) below it (e.g. 2023-12a, b, c etc.).* New issue reports published starting from January 1, 2024 must meet this criterion, as versions below the latest releases are no longer supported by us.
+5. When reporting a problem, please be as detailed as possible and include even the smallest changes to your mailcow installation. Simply fill out the corresponding bug report form in detail and accurately to minimize possible questions.
+6. **Before you open an issue/feature request**, please first check whether a similar request already exists in the mailcow tracker on GitHub. If so, please include yourself in this request.

-         LRUCache, based on a synchronized LinkedHashMap, and
-         FastLRUCache, based on a ConcurrentHashMap.
-
-         FastLRUCache has faster gets and slower puts in single
-         threaded operation and thus is generally faster than LRUCache
-         when the hit ratio of the cache is high (> 75%), and may be
-         faster under other scenarios on multi-cpu systems.
-    -->
-
-    <!-- Filter Cache
-
-         Cache used by SolrIndexSearcher for filters (DocSets),
-         unordered sets of *all* documents that match a query.  When a
-         new searcher is opened, its caches may be prepopulated or
-         "autowarmed" using data from caches in the old searcher.
-         autowarmCount is the number of items to prepopulate.  For
-         LRUCache, the autowarmed items will be the most recently
-         accessed items.
-
-         Parameters:
-           class - the SolrCache implementation LRUCache or
-               (LRUCache or FastLRUCache)
-           size - the maximum number of entries in the cache
-           initialSize - the initial capacity (number of entries) of
-               the cache.  (see java.util.HashMap)
-           autowarmCount - the number of entries to prepopulate from
-               and old cache.
