"Zend\Mail\Message" not found in Magento 2.4.6-p3

[FremRon]

The magento mailjet module is affected by this bug :
magento/magento2#38421

To sum up : when dependency laminas/laminas-server is updating from v2.16.0 to v2.17.0, this cause laminas/laminas-zendframework-bridge to be removed. This package is required by a lot of 3rd party SMTP extensions that still use Zend\Mail as is Mailjet module.

The fix is to switch from Zend to Laminas.
