JavaMail剔除邮件

JavaMail删除邮件

最近有个邮件的任务，其中有个功能是要删除邮件服务器的邮件

在网上找了几种方式都有点问题，一直是报：POP3 messages are read-only

修改了下代码就可以删除了，本次只做了下QQ邮箱的测试

        Properties props = new Properties();        // props.setProperty("mail.smtp.host", "smtp.sina.com");        props.setProperty("mail.smtp.auth", "true");       //props.setProperty("mail.transport.protocol", "smtp");        Session session = Session.getDefaultInstance(props,null);        URLName urlname = new URLName("pop3","pop.qq.com",110,null,"xxxxx","xxxxx");       //URLName urlname = new URLName("pop3","pop.exmail.qq.com",110,null,"xxxxx","xxxxx");        Store store = session.getStore(urlname);        store.connect();        Folder folder = store.getFolder("INBOX");       // folder.open(Folder.READ_ONLY);        folder.open(Folder.READ_WRITE);        Message msgs[] = folder.getMessages();        int count = msgs.length;        System.out.println("Message Count:"+count);         msgs[count-1].setFlag(Flags.Flag.DELETED, true);          //msgs[count-1].saveChanges();        //folder.expunge();        folder.close(true);        store.close();
