JavaMail客户端读取新消息但不读取现有消息

标签： email javamail imap

JavaMail新手在这里。我试图弄清楚嵌入在一个非常大的系统中的Javamail客户端有什么问题。对不起，我没有一个简短的，自包含的示例，但我希望有人可以给我一些关于如何调试此问题的提示。

它是Java 7中的JavaMail 1.4.3，在Windows 7上运行。电子邮件服务器位于Linux机器上。代码的目的是读取收件箱中的所有电子邮件，删除和清除它们，对电子邮件做一些工作，暂停一段时间，然后重复，永远循环。问题是，如果此程序启动时收件箱中已有电子邮件并且JavaMail客户端代码已执行，则它不会检索它们。但是，如果我在代码运行后将电子邮件发送到收件箱，它会很好地检索它们。

代码使用Store.getFolder（“INBOX”）获取收件箱，使用Folder.open（Folder.READ_WRITE）打开它并执行Folder.getMessages（）。 getMessages（）调用在第一次启动时始终不返回任何消息，但会返回在程序启动后发送的消息。

我正在使用Pine来验证收件箱是否包含消息，但是我没有打开Pine中的消息，所以它们仍然是新的。如果我在运行此代码后使用Pine查看收件箱，它仍然包含在程序启动之前发送的旧消息，但不包含在程序运行时发送给它的任何消息（它们已成功读取，删除并删除）。

代码还应该在启动时读取收件箱中已有的邮件。我设置mail.debug = true，然后输出。再次，任何有关如何深入研究这一点的提示将不胜感激。感谢。

答案 0 :(得分：0)

您的服务器告诉JavaMail，首次打开收件箱时，收件箱中没有邮件（“0 EXISTS”），然后会出现一条消息（“1 EXISTS”），程序会处理，删除和删除。这一切看起来都很正常。

如果您认为收件箱中还有其他邮件，则服务器不同意。也许你在Pine客户端缓存了一些消息？也许您已将Pine设置为与大多数POP3客户端的工作方式类似 - 从服务器下载邮件，在本地缓存它们，并从服务器中删除它们？
