I would like to make a filter for all the history traffic in a MUC. I notice that Spark can do this as it displays message history in grey color and new messages in black/color. Is this functionallity provided though Smack? Any ideas will be appreciated. Thanks.
as far as I understand this the server sends some (default 25) messages (configured here if you are using Wildfire /muc-history-settings.jsp) as history. I did not use the Spark XMPP debugger, but I assume that some values are set so every client can detect them as history.
