最近写了一个javamail通过smtp发送邮件的代码，在本机上测试一切OK，当我放到服务器上的时候，报AuthenticationFailedException异常，验证我也加上去了，找了半天也没找出原因，请大家帮忙看看，下面是我的代码
public class SendMailAgent {
private MimeMessage mimeMsg; //MIME邮件对象
private Session session; //邮件会话对象
private Properties props; //系统属性
private boolean needAuth = true; //smtp是否需要认证
private String hostName = constantVar.EMAIL_SERVER;
private String username = constantVar.EMAIL_ACCOUNT; //smtp认证用户名和密码
private String password = constantVar.EMAIL_PASSWORD;
private String from = constantVar.EMAIL_MANAGER;
private Multipart mp; //Multipart对象,邮件内容,标题,附件等内容均添加到其中后再生成MimeMessage对象
/* public SendMailAgent() {
setSmtpHost(ConsConfig.mailHost);//如果没有指定邮件服务器,就从getConfig类中获取
createMimeMessage();
}**/

//System.out.println(hostName);
setSmtpHost();
createMimeMessage();
}

建议用apache组件
很方便！就10几行代码就搞定， |

这个函数
setNeedAuth(boolean need) 虽然设置了true，但是你还是没有进行验证啊，应该在获取会话之前加上以下代码
Authenticator auth = new Authenticator() {
public PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(user, password);//你的邮箱用户名和密码
}
};
Session s = Session.getInstance(p,auth);
还有你215行这里，临时变量mailSession只是为了发送邮件，为什么不用全局变量session啊？ 你试试吧。我在邮件发送过程中也是问题很多，汗啊........ |
