Discussed in #9632

Hi,
it looks like after merging PR#9546 the returned values from AbstractMailReceiver#receive no longer reflect the current state of the MimeMessage after the receiving process.
The message flags of the received messages are outdated and don't contain the changes of AbstractMailReceiver#setMessageFlags, because the flags are only applied to the original message and not the copy (AbstractMailReceiver.IntegrationMimeMessage).
The behavior change can be verified by debugging the returned values from receiver.receive() in the new unit test method. The flags are empty in the debugger, while the original messages (msg1, msg2) contain the flags \Seen and spring-integration-mail-adapter.
Was this change in behavior intentional? This looks like a bug to me, because message processing after the initial receiving step now works with an outdated state.
Best regards,
Daniel
