Your TYPO3 site sends emails, but they never arrive — or worse, they land in spam. Common causes: - **SPF misconfiguration**: Your SMTP server isn't authorized to send for your domain - **Missing DKIM**: Emails aren't signed, reducing trust - **No DMARC policy**: Receiving servers don't know how to handle authentication failures - **Invalid addresses**: Typos or non-existent sender addresses cause bounces - **Missing MX records**: The sender domain can't receive replies These issues are invisible until someone reports missing emails. By then, you've lost form submissions, notifications, and customer trust. The Solution ------------ [](#the-solution) This extension validates sender addresses *before* they cause problems. Configure your sender addresses once, validate them, and use them across your TYPO3 site with confidence. What Gets Validated ------------------- [](#what-gets-validated) CheckWhat It Does**Email Syntax**Validates RFC 5322 compliance — catches typos and malformed addresses**MX Records**Confirms the domain has mail servers configured**SPF**Verifies your TYPO3 SMTP server is authorized to send for this domain**DKIM**Checks email signatures are properly configured (requires test email)**DMARC**Analyzes authentication policy and provides recommendations**Email Existence**Confirms the mail server accepts the addressValidation runs automatically and results are cached. Upload a test email (EML file) for complete SPF/DKIM/DMARC validation against your actual mail flow. Features -------- [](#features) - Manage sender addresses in the TYPO3 backend - Visual validation status in the record list - CLI command: `mail:sender:validate` - Integration with TYPO3 System Information module - Integration with ext:form (validated sender dropdown) - Scheduler task for periodic re-validation Screenshots ----------- [](#screenshots) ### Backend Module [](#backend-module) [![Mail Sender Backend Module](Documentation/Images/backend-module-overview.png)](Documentation/Images/backend-module-overview.png) *Manage sender addresses with validation status, scheduled re-validation, and webhook notifications.* ### Validation Details [](#validation-details) [![Validation Results](Documentation/Images/validation-results.png)](Documentation/Images/validation-results.png) *Detailed validation results showing individual checks for syntax, MX, SPF, DKIM, DMARC, and email existence.* ### System Reports Integration [](#system-reports-integration) [![Reports Integration](Documentation/Images/reports-integration.png)](Documentation/Images/reports-integration.png) *Integration with TYPO3 System Reports showing sender address status at a glance.* Requirements ------------ [](#requirements) - TYPO3 12.4, 13.4 or 14.3 (LTS) - PHP 8.1 or later (TYPO3 14 requires PHP 8.2+) - Optional: `mika56/spfcheck` for full SPF validation Installation ------------ [](#installation) ``` composer require hn/typo3-mail-sender ``` Usage ----- [](#usage) ### Managing Sender Addresses [](#managing-sender-addresses) 1. Navigate to the **List** module 2. Select the **root page** (ID: 0) 3. Create new **"Mail Sender Address"** records Each record contains: - **Sender Email Address**: The email to use as sender - **Sender Name**: Display name for the sender - **EML File**: Optional test email for SPF/DKIM/DMARC validation ### CLI Validation [](#cli-validation) Validate all sender addresses: ``` vendor/bin/typo3 mail:sender:validate ``` Validate a specific address: ``` vendor/bin/typo3 mail:sender:validate --email=info@example.com ``` ### Integration with ext:form [](#integration-with-extform) The extension provides a `SenderEmailAddress` form element that shows a dropdown of validated sender addresses instead of a freetext field. Development ----------- [](#development) ### Running Tests [](#running-tests) Functional / unit tests (host PHP + SQLite): ``` composer test ``` #### End-to-end tests (Playwright) [](#end-to-end-tests-playwright) The end-to-end suite drives a real TYPO3 backend with Playwright and verifies the three user-facing surfaces against all supported TYPO3 versions (12.4, 13.4, 14.3): 1. the **ext:form integration** (the validated sender-address dropdown is injected into the form editor and the form can be saved), 2. the **validation backend module** (lists sender addresses and revalidates), 3. the **List module** (lists and creates Mail Sender Address records). ``` # Run against the currently installed TYPO3 version Build/runTests.sh -s e2e --no-docker # Run against a specific TYPO3 version (installs it via composer) Build/runTests.sh -s e2e -t 12.4 --no-docker Build/runTests.sh -s e2e -t 13.4 --no-docker Build/runTests.sh -s e2e -t 14.3 --no-docker ``` The runner sets up an SQLite-backed TYPO3 instance, seeds a validated sender address and a form definition, starts the PHP built-in web server and runs the Playwright specs in `Build/tests/playwright/`. CI runs the same suite across the three versions (see `.github/workflows/tests.yml`). ### Test Coverage [](#test-coverage) - Basic CRUD operations - Record soft-delete and visibility - TCA configuration - Database schema - End-to-end coverage of the form editor, validation module and List module Contributing ------------ [](#contributing) We welcome contributions from the TYPO3 community! - Share feedback via [GitHub Issues](https://github.com/hauptsacheNet/typo3-mail-sender) - Report bugs - Improve documentation - Submit pull requests Roadmap ------- [](#roadmap) ### Phase 1: Foundation ✅ [](#phase-1-foundation-) Basic extension structure with sender address management in the TYPO3 backend. ### Phase 2: Core Validation ✅ [](#phase-2-core-validation-) Complete email validation system with DNS checks, SPF/DKIM/DMARC analysis, and status reporting. ### Phase 3: Integration & Adoption 🔄 [](#phase-3-integration--adoption-) - ✅ Integration with ext:form - 📋 TCA Extra Field API for third-party extensions - 📋 Documentation for extension developers ### Phase 4: Polish & Import 🔄 [](#phase-4-polish--import-) - ✅ Import from `$GLOBALS['TYPO3_CONF_VARS']['MAIL']` - 📋 Import from TypoScript configurations - 📋 Reference tracking (where sender addresses are used) - 📋 TER release **Target Release:** December 2025 License ------- [](#license) GPL-2.0-or-later Authors ------- [](#authors) - **Marco Pfeiffer** — - **TYPO3 Community** — Funded by Community Budget Q4 2025 ### Health Score 42 — FairBetter than 88% of packages Maintenance87 Actively maintained with recent releases Popularity20 Limited adoption so far Community10 Small or concentrated contributor base Maturity43 Maturing project, gaining track record Bus Factor1 Top contributor holds 88.6% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
