JavaMail Hotmail 获取文件夹列表

Question

我想查看我的 hotmail 帐户中除收件箱之外的其他文件夹。

String host = "pop3.live.com";
String username = "peepants@hotmail.com";
String password = "peepantspants";
Properties pop3Props = new Properties();
pop3Props.setProperty("mail.pop3s.port",  "995");
Session session = Session.getInstance(pop3Props, null);
Store store = session.getStore("pop3s");
store.connect(host, 995, username, password);

Folder folder = store.getFolder("INBOX");    //this works fine
folder.open(Folder.READ_WRITE);

Folder[] f = store.getDefaultFolder().list("*");
for (int i = 0; i < f.length; i++ )
    System.out.println( f[i].getFullName() );    //this only prints INBOX

Folder ofolder = store.getFolder("MyOtherFolder");    //this doesn't work
ofolder.open(Folder.READ_WRITE);

Message messages[] = folder.getMessages(); 
folder.copyMessages(new Message[]{messages[0]}, ofolder);    //this doesn't work

除了收件箱，我无法进入任何其他文件夹。

store.getFolder("MyOtherFolder")

抛出以下错误

Exception in thread "main" javax.mail.FolderNotFoundException: folder is not INBOX
    at com.sun.mail.pop3.POP3Folder.open(POP3Folder.java:199)

Answer 1

你不能。 POP3 协议(protocol)只支持单个邮箱。据我所知，Hotmail 仍然不支持任何其他允许访问其他邮箱的标准协议(protocol)，例如 IMAP。
