Question

我使用普通的旧邮件（mail-1.4.1.jar - JVM 1.6.0_03-b05）连接到IMAP商店：

Session mailSession = Session.getInstance(new Properties(), null);
Store store = mailSession.getStore("imap");
store.connect(host, user, pwd); // Hangs here
folder = store.getFolder("INBOX");
folder.open(Folder.READ_WRITE);
...

问题是，线程偶尔交给store.connect并且永远不会返回。

javamail spec中没有提及超时设置，我在Session或Store上找不到任何合适的'setter'方法。

欢迎任何建议。

请参阅com.sun.mail.imap package的javadocs，了解可以设置控制的属性（以及其他内容）超时。哦，您可能想要升级到最新版本的JavaMail。

java mail Store.connect hangs - 不会超时
