使用James邮件服务器遇到问题很受伤(但是后来发现是“乌龙”,囧)

James2.3.2运行在ubuntu上面，ruby也在上面，本地代码测试发邮件居然错误。
Jame运行后，在里面增加两个账号paul和sandy。
smtpserver日志，AUTH method LOGIN failed这样的错误信息根本搞不清楚根本原因。

James配置，修改部分

增加了一个servername配置    
<servernames autodetect="true" autodetectIP="true">
<!-- CONFIRM? -->
         <servername>localhost</servername>
		 <servername>ubuntu</servername>
      </servernames>
需要登录
         <authRequired>true</authRequired>

----------------------------------------------------------------------
ruby代码

require 'net/smtp' 

    msg = "Subject: Sendmail test Hi There!\n\nThis works, and this part is in the body." 
    smtp = Net::SMTP.new 'localhost', 25
    #smtp.enable_starttls 
    smtp.start('localhost','paul@localhost', '123456', :login) do 
      smtp.send_message(msg, 'paul@localhost',  'sandy@localhost') 
    end 

报错误

基本怀疑James auth plain有bug，没有心情去继续深入追究，换邮件服务器。

Which tells us that AUTH PLAIN isn't in wide use.

It appears that our AUTH PLAIN implementation is wrong.  Outlook works
because it uses AUTH LOGIN, which we do have implemented properly.

I have a fix locally, and will commit to CVS.  It is a one liner, if you
want to make it in your copy.

You do realize that you have to change your password, right?  You just gave
it out to everyone.

又经过一些时间分析，使用比较熟悉的Java代码来测试，发现上面的ruby代码有潜在问题，估计是协议支持问题，后续再多花时间分析。

public void sendlocal(String[] args){
		
		String host = "localhost";
	    String from = "paul@localhost";
	    String[] to = {"sandy@localhost"}; // added this line
        if(args!=null){
		
			to=new String[]{args[0]};
		
			if(args.length>=2&&args[1]!=null){
				from=args[1];
			}
		}
	    String pass = "123456";
	    Properties props = System.getProperties();
	    //props.put("mail.smtp.starttls.enable", "true"); // added this line
	    props.put("mail.smtp.host", host);
	    props.put("mail.smtp.user", from);
	    props.put("mail.smtp.password", pass);
	    props.put("mail.smtp.port", "25");
	    props.put("mail.smtp.auth", "true");

	   

	    Session session = Session.getDefaultInstance(props, null);
	    MimeMessage message = new MimeMessage(session);
	    try {
			message.setFrom(new InternetAddress(from));
		    InternetAddress[] toAddress = new InternetAddress[to.length];

		    // To get the array of addresses
		    for( int i=0; i < to.length; i++ ) { // changed from a while loop
		        toAddress[i] = new InternetAddress(to[i]);
		    }
		    System.out.println(Message.RecipientType.TO);

		    for( int i=0; i < toAddress.length; i++) { // changed from a while loop
		        message.addRecipient(Message.RecipientType.TO, toAddress[i]);
		    }
		    message.setSubject("Sending in a group");
		    message.setText("Welcome to JavaMail");
		    
		    Transport transport = session.getTransport("smtp");
		    transport.connect(host, from, pass);
		    transport.sendMessage(message, message.getAllRecipients());
		    transport.close();
		    System.out.println("send mail correct!!");
		} catch (AddressException e) {
		
			e.printStackTrace();
		} catch (MessagingException e) {
			
			e.printStackTrace();
		}
