12.10.2

Description

I've implemented a custom mail transport as described here:
https://laravel.com/docs/12.x/mail#custom-transports

The example on the documentation page shows how to convert SentMessage to Email object:

$email = MessageConverter::toEmail($message->getOriginalMessage());

phpstan (level 5) complains about the data types:

app/Mail/Transports/SESTransport.php:23:Parameter #1 $message of static method Symfony\Component\Mime\MessageConverter::toEmail() expects Symfony\Component\Mime\Message, Symfony\Component\Mime\RawMessage given.

It seems that phpstan is right, the data types are not strictly compatible.
It actually works without crashing though.
I know I can ignore this phpstan issue, but it would be nice to have it fixed.

How to reproduce

• Implement the custom mail transport like in the documentation (copy/paste) from the link above.
• Run phpstan with level 5
