Question

这个问题从一个相当模糊的问题演变成一个更明确的问题。代码来自example by mkyong。至少根据谷歌，it's a bad password，我已经按照他们的登录建议。当然，在输入正确的密码时我得到相同的结果，下面的密码是假的。无论密码如何，它都是相同的输出。

输出：

因为您要连接到Gmail。使用这些属性

prop.put("mail.smtp.starttls.enable", "true"); 
prop.put("mail.smtp.host", host); 
prop.put("mail.smtp.user", from); 
prop.put("mail.smtp.password", pass); 
prop.put("mail.smtp.port", "465"); 
prop.put("mail.smtp.auth", "true");
