Description

Cannot send email messages using the async transport and the sender address configuration. Exception thrown:

"An email must have a "From" or a "Sender" header."

How to reproduce

Set the sender address in the configuration:

framework:
    mailer:
        dsn: '%env(MAILER_DSN)%'
        envelope:
            sender: no-reply@example.com
        headers:
            From: 'Example <no-reply@example.com>'

Send an email without using any transport (sync sending): OK

Send an email using the async transport: KO

Error thrown while handling message Symfony\Component\Mailer\Messenger\SendEmailMessage. Sending for retry #1 using 1060 ms delay. Error: "An email must have a "From" or a "Sender" header." {"class":"Symfony\Component\Mailer\Messenger\SendEmailMessage","message_id":77,"retryCount":1,"delay":1060,"error":"An email must have a "From" or a "Sender" header.","exception":"[object] (Symfony\Component\Mime\Exception\LogicException(code: 0): An email must have a "From" or a "Sender" header. at /app/vendor/symfony/mime/Message.php:132)"} []

Async transport configuration:

framework:
    messenger:
        # Uncomment this (and the failed transport below) to send failed messages to this transport for later handling.
        failure_transport: failed

        transports:
            # https://symfony.com/doc/current/messenger.html#transport-configuration
            async: '%env(MESSENGER_TRANSPORT_DSN)%'
            failed: 'doctrine://default?queue_name=failed'
            # sync: 'sync://'

        routing:
            # Route your messages to the transports
            # 'App\Message\YourMessage': async
            Symfony\Component\Mailer\Messenger\SendEmailMessage: async

Possible Solution

No response

Additional Context

The EnvelopeListener which I suppose is responsible of setting the sender is actually called even using the async transport.
