>             Project: Camel
>          Issue Type: Bug
>          Components: camel-mail
>    Affects Versions: 2.15.3
>            Reporter: Jussi Nupponen
>         Attachments:, camel-mail.mapMailMessages-peek.patch,
trace-bug.log, trace-fixed.log
> URI option mapMailMessage=true as is the default with Mail Component fetches IMAP-messages
without peek=true option. This results to faulty rollback logic since in case of an exception
and rollback, messages are already marked with flag SEEN and won't be rolled back to UNSEEN.
> Messages are marked with peek-option in processBatch-method but mapping mail messages
to Camel messages happens before that method call in createExchanges-method.
> I've attached a patch where peek option is set to the messages already in the poll-method
which resolves the issue. Unfortunately I couldn't write a proper jUnit test for this scenario
since org.jvnet.mock_javamail.Mailbox doesn't seem to support marking messages as SEEN even
if they have been fetched.  However, I have attached traces of faulty and fixed run with a
test route (that route is also included).
