TYPO3 Mail Routing Extension

A TYPO3 CMS extension that enables flexible e-mail transport routing. This extension allows you to control which mail transport is used for sending emails either globally for your entire site or on a per-email basis.

Features

• Route emails to different transports using the X-Mail-Transport header
• Configure a default transport for a certain site
• Override the default transport on a per-email basis by setting the X-Mail-Transport header
• Seamless integration with TYPO3's mail system
• Support for multiple mail transport configurations
• Easy to extend and customize

Requirements

• PHP 8.1 or higher
• TYPO3 CMS 13.4.5 or higher

Installation

1. Install via Composer:

composer require mfd/typo3-mail-routing

2. Include the extension in your TYPO3 installation:
   • Activate the extension in the TYPO3 Extension Manager
   • Or include it in your composer.json and run composer update

Configuration

The extension is configured through EXTCONF settings that follow the same conventions as TYPO3's mail configuration ($GLOBALS['TYPO3_CONF_VARS']['MAIL']). You can configure these settings in your config/system/additional.php file:

$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['mail_routing'] = [
    'transports' => [
        'special_smtp' => [
            'transport' => 'smtp',
            'host' => 'smtp.example.org',
            'port' => 25,
            // ... other SMTP settings
        ],
        'sendmail' => [
            'transport' => 'sendmail',
            'command' => '/usr/sbin/sendmail -bs',
        ],
    ]
    // Add more transport configurations as needed
];

Each transport configuration should match the structure expected by TYPO3's mail system. The default key specifies which transport to use when no specific transport is requested.
