I want to know what do I have to do in my mail application to move rest of the messages of marking any email address as spam into spam folder without restarting mail server. Actually I can move the messages into spam folder, but I have do some configuration in my mail server, then have to restart it before making it move to spam folder in mail server itself. Can I do this stuff dynamically through Javamail? Do I have to use JDBC connectivity to store marking any email address messages as spam into database table? How Yahoomail or Gmail do?
