JAVAMAIL邮件接收开发

javamail读取邮件报:javax.mail.AuthenticationFailedException: EOF on socket解决办法：
如果连接邮件服务器、端口号、用户名、密码没有问题那就可能是一些认证没有被通过，我的这个问题是没有设置SSL认证所导致，在连接时添加如下：

Properties pop = new Properties();
//SSL认证
pop.setProperty("mail.pop3.socketFactory.class" , "javax.net.ssl.SSLSocketFactory");
pop.setProperty("mail.pop3.socketFactory.port",port);
//还有其它一些认证或其它的:
pop.put("mail.smtp.auth", "true");
		pop.put("mail.smtp.starttls.enable",Config.getConfig("mail-server","starttls"));
		pop.put("mail.smtp.host", host); 
		pop.put("mail.mime.address.strict", "false");
		pop.put("mail.smtp.connectiontimeout", Config.getConfig("mail-server", "connect-timeout"));
		pop.put("mail.smtp.timeout", Config.getConfig("mail-server", "send-timeout"));
		PopAuthenticator authenticatior = null;
		if (Config.getConfig("mail-server", "authenticate").equalsIgnoreCase("TRUE")) {
			authenticatior = new PopAuthenticator();
			authenticatior.performCheck(userName, passWord);
		}
	
		this.session = Session.getDefaultInstance(pop, authenticatior);
Folder folder = null;
		Store store = null;
		try {
//这种方法也可以连接
		   /* URLName urln = new URLName("pop3",host, Integer.parseInt(port), null,userName, passWord);
		    store = session.getStore(urln);
		    store.connect();*/
			store = session.getStore("pop3");
			if(port != null && !port.equals("")) {
				store.connect(host,Integer.parseInt(port), userName, passWord); 
			}else {
				store.connect(host, userName, passWord); 
			}
			folder = store.getFolder("INBOX");
			folder.open(Folder.READ_WRITE);
			Message[] message = folder.getMessages();
			log.info("all mail size = " + message.length);
			
		} catch (MessagingException e) {
			log.error("邮件服务器连接错误!"+e.getMessage());
			e.printStackTrace();
		} catch(Exception e){
			log.error(e.getMessage());
			e.printStackTrace();
		}finally {
			try {
				if (folder != null)
					folder.close(true);
				if (store != null)
					store.close();
			} catch (MessagingException e) {
				e.printStackTrace();
			}
		}
