Maintain IMAP message state information (imap flags) when using Javamail
-

Question
We have a java app built by third party that opens a read/write IMAP connections, and retrieves certain messages. However it also marks them as "read". I am guessing this is due to fact that the app opens a read/write connection. Is there a way we can prevent this app from updating the "read (seen)" imap flag? Maybe a parameter we can set when opening the connection to the IMAP?

You can do this for a single message:
folder.setFlags(new Message[] {message}, new Flags(Flags.Flag.SEEN), false);
or for a list of messages:
folder.setFlags(messageList, new Flags(Flags.Flag.SEEN), false);
where false
stands for UNREAD.
