After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

TYPO3 Extension: Mail Sender Configuration

Configure and validate email sender addresses with DNS and deliverability checks for TYPO3 CMS.

The Problem

Email delivery fails silently. Your TYPO3 site sends emails, but they never arrive — or worse, they land in spam. Common causes:

These issues are invisible until someone reports missing emails. By then, you've lost form submissions, notifications, and customer trust.

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

Check What 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 address

Validation runs automatically and results are cached. Upload a test email (EML file) for complete SPF/DKIM/DMARC validation against your actual mail flow.

CLI Validation

Validate a specific address:

Integration with ext:form

The extension provides a SenderEmailAddress form element that shows a dropdown of validated sender addresses instead of a freetext field.

Development

Running Tests

Functional / unit tests (host PHP + SQLite):

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).

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).
