Guys, I think this is a bug, but thought I'd post here before Jira. In the getBoundary() method in MessageData, I think the line: String[] header = getHeader("Content-Type").split("\\r\\n"); Should be moved into the try/catch. If a message doesn't have a Content-Type, the method crashes. Not sure how the writeMessage in CmdRETR in the pop3 handlers would handle this, but I'm using similar code to read messages via a servlet and this issue just popped up for us. -Pat View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3961320#...
