> By default, if you access the content of an IMAPMessage, it will be flagged as SEEN on the server. This creates a problem if the route is subsequently rolled back (due to an exception - e.g. connection error on destination endpoint), the message will remain as SEEN and never get picked up on subsequent polls (unseen=true).
> setPeek(true) should be called on each IMAPMessage before being dispatched to the processor; this ensures that the message will not be automatically flagged as SEEN before being fully consumed.
> As a work around, implement a custom processor that calls setPeek(true) on the original IMAPMessage (using reflection):
> {quote}
> Message msgIn = exchange.getIn();
> Field f = msgIn.getClass().getDeclaredField("originalMailMessage");
> f.setAccessible(true);
> IMAPMessage im = (IMAPMessage) f.get( msgIn );
> im.setPeek(true);
> {quote}
> For reference, this is my route configuration:
> {quote}
> from("imap://sn?username=un&password=xx&delete=false&unseen=true").
> process( new MyCustomAttachmentProcessor() ).
> to("jms://xyz");
> {quote}
