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.comheaders: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:failedtransports:# https://symfony.com/doc/current/messenger.html#transport-configurationasync:'%env(MESSENGER_TRANSPORT_DSN)%'failed:'doctrine://default?queue_name=failed'# sync: 'sync://'routing:# Route your messages to the transports# 'App\Message\YourMessage': asyncSymfony\Component\Mailer\Messenger\SendEmailMessage:async

Possible Solution

No response

Additional Context

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