我试图通过Eclipse中的IMAP和POP3（使用javamail）接收来自gmail和outlook的电子邮件。但每次我看到相同的错误信息。
使用IMAP和Gmail接收：
Properties props = new Properties();
props.setProperty("mail.store.protocol", "imaps");
props.setProperty("mail.imap.host", "imap.gmail.com");
props.setProperty("mail.imap.port", "993");
props.setProperty("mail.imap.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.setProperty("mail.imap.socketFactory.fallback", "false");
Session imapSession=Session.getInstance(props);
Store store = imapSession.getStore("imaps");
store.connect("imap.gmail.com","gmail account", "pass");
Folder inbox = store.getFolder("Inbox");
inbox.open(Folder.READ_WRITE);
Message[] msgs =inbox.getMessages();
Message read=msgs[1];
String result=read.toString();
return result;
错误日志：

使用POP3和Outlook：
Properties properties = new Properties();
properties.put("mail.pop3.host", "pop-mail.outlook.com");
properties.put("mail.pop3.port", "995");
properties.put("mail.pop3.starttls.enable", "true");
Session emailSession = Session.getDefaultInstance(properties);
Store store = emailSession.getStore("pop3s");
store.connect("pop-mail.outlook.com", "username", "pass");
Folder emailFolder = store.getFolder("INBOX");
emailFolder.open(Folder.READ_ONLY);
Message[] messages = emailFolder.getMessages();
String result=messages[10].toString();
emailFolder.close(false);
store.close();
return result;

我可以统计收到的邮件数量但是没有运气阅读它们。我几乎是Android新手，但据我所知，javamail库出了问题。
