# Description of Changes

Please provide a summary of the changes, including:

- **What was changed**  
- **EmailController**: Added a `catch (MailSendException)` block to
handle invalid-address errors, log the exception, and return a 500
response with the raw error message.
- **EmailServiceTest**: Added unit tests for attachment-related error
cases (missing filename, null filename, missing file, null file) and
invalid “to” address (null or empty), expecting `MessagingException` or
`MailSendException`.
- **MailConfigTest**: New test class verifying `MailConfig.java`
correctly initializes `JavaMailSenderImpl` with host, port, username,
password, default encoding, and SMTP properties.
- **EmailControllerTest**: Refactored into a parameterized test
(`shouldHandleEmailRequests`) covering four scenarios: success, generic
messaging error, missing `to` parameter, and invalid address formatting.

- **Why the change was made**  
- To ensure invalid email addresses and missing attachments are handled
gracefully at the controller layer, providing clearer feedback to API
clients.
- To improve overall test coverage and guard against regressions in
email functionality.
  - To enforce correct mail configuration via automated tests.

+This file provides high-level instructions for Codex when modifying any files within this repository. Follow these rules to ensure changes remain consistent with the existing project structure.
+
+## 1. Code Style and Formatting
+- Respect the `.editorconfig` settings located in the repository root. Java files use 4 spaces; HTML, JS, and Python generally use 2 spaces. Lines should end with `LF`.
+- Format Java code with `./gradlew spotlessApply` before committing.
+- Review `DeveloperGuide.md` for project structure and design details before making significant changes.
+
+## 2. Testing
+- Run `./gradlew build` before committing changes to ensure the project compiles.
+- If the build cannot complete due to environment restrictions, DO NOT COMMIT THE CHANGE
+
+## 3. Commits
+- Keep commits focused. Group related changes together and provide concise commit messages.
+- Ensure the working tree is clean (`git status`) before concluding your work.
+
+## 4. Pull Requests
+- Summarize what was changed and why. Include build results from `./gradlew build` in the PR description.
+- Note that the code was generated with the assistance of AI.
+
+## 5. Translations
+- Only modify `messages_en_GB.properties` when adding or updating translations.

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
