While I get the motivation for introducing this QueuingMessageEvent child event in #47191, it's a BC break that is difficult to circumvent due to the fact it's an event (the parent may still be used as it's not deprecated).
So I propose to revert its addition and just add the needed stamp-related methods to the original event instead.

@chalasr will this fix #47383 as well like I think it will?

[chalasr]

@nesl247 Yes it does, thanks for noticing and testing dev branches.

Sorry to hijack this thread, but wanted to confirm that after this merge, the profiler is still confused and showing 2 emails sent in the left menu and 1 queued and 1 sent.

Is this on purpose or something else that needs fixing?

My code is only sending one email.

  $message = new Email();
        $message->to('phil@phil-taylor.com')
            ->from('phil@phil-taylor.com')
            ->subject('Mailer Test')
            ->text('This is just a test');

        $mailer->send($message);

I'll have a look today, thanks for telling us.

@PhilETaylor I can't reproduce on a basic setup sorry, I get only one queued email reported in the profiler panel. Please make sure it's not an issue in your code and if it's not, consider opening an issue with a minimal application that allows reproducing the issue. Thanks

yes, 30 seconds ago I tested my symfony demo site and I could also not reproduce it - dang it! Sorry for wasting your time, I'll dig deeper.

The [main] transport is confusing though, as my only transport is the smtp://mailhog... one...

edit: Should also say, 6.1 gives only 1 email in the profiler, not 2 - dang it :) :)

ok I fired up the laptop which has never seen 6.2 and now I can replicate my issue in my app only in 6.1.4 - sorry for the noise... only one email is every sent to the MAILER_DSN but something is also queuing an email - ill shut up now and go debug more ... sorry for wasting your time on this side show.
