symfony: Memory Leak in Symfony Mailer when sending many attachments of >5MB

Symfony version(s) affected

5.4.22

Description

Hi , I have encountered an issue where attaching several files each of size 5MB , sends Out Of Memory exception Uncaught PHP Exception Symfony\Component\ErrorHandler\Error\OutOfMemoryError: "Error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 23079128 bytes)" at vendor/symfony/mime/RawMessage.php line 53 {"exception":"[object] (Symfony\\Component\\ErrorHandler\\Error\\OutOfMemoryError(code: 0): Error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 23079128 bytes) at vendor/symfony/mime/RawMessage.php:53)"} [

Is that a known issue. or am I missing something ?

I have already tried using attachPart, attach , but it produces the same results.

How to reproduce

Attach numerous Files from form to be sent in email each of size 5MB .
