Haerriz SMTP Routing for Magento 2
==================================

[](#haerriz-smtp-routing-for-magento-2)

A lightweight Magento 2 module that dynamically intercepts outgoing emails and swaps the SMTP authentication credentials based on the `From` email address.

This is extremely useful for shared hosting environments (like Hostinger) that enforce strict anti-spoofing policies (e.g., `553 Sender address rejected: not owned by user`), requiring the SMTP login to match the exact outgoing email address.

Features
--------

[](#features)

- Bypasses strict anti-spoofing policies on shared hosting.
- Natively intercepts Magento's core `Magento\Email\Model\Transport` via a lightweight Plugin.
- Pulls credentials securely from Magento's `env.php` without hardcoding passwords in the database.
- Completely eliminates the need for bulky, paid SMTP extensions.

Installation via Composer
-------------------------

[](#installation-via-composer)

```
composer require haerriz/module-smtprouting
bin/magento module:enable Haerriz_SmtpRouting
bin/magento setup:upgrade
bin/magento setup:di:compile
```

Configuration
-------------

[](#configuration)

1. In your server's `app/etc/env.php`, add an array mapping your sender emails to their SMTP passwords:

```
'smtp_mapping' => [
    'orders@yourstore.com' => 'orders_password',
    'newsletter@yourstore.com' => 'newsletter_password',
    'support@yourstore.com' => 'support_password'
],
```

2. Configure your primary Magento SMTP fallback credentials in `Stores > Configuration > Advanced > System > SMTP` as usual. If an email is sent that does not match a specific mapping in `env.php`, it will fall back to the primary credentials.
