java - 无法从 Yahoo IMAP 帐户删除邮件

Question

我的要求是我想从我的 Yahoo 帐户中删除邮件，所有代码在我的 Gmail 帐户上运行良好。

下面是删除代码-

   Message msg[] = inbox.getMessages();
   inbox.setFlags(msg, new Flags(Flags.Flag.DELETED), true);

执行上述代码行后，我不会关闭文件夹。由于我在设置 DELETED 标志后无法关闭文件夹，因为我的代码正在并行运行以删除多个文件夹的多条消息。

下面是 Gmail 和 Yahoo 删除两条消息的协议(protocol)跟踪 -

我发现在这两种情况下设置 DELETED 标志并且不关闭文件夹，然后如果我调用 -

 Message msg[] = inbox.getMessages();

协议(protocol)跟踪的主要区别 -

Gmail 显示

* 1 EXPUNGE
* 1 EXPUNGE
* 0 EXISTS

雅虎显示 -

* 2 EXISTS
* 0 RECENT

尽管我的代码没有更改，也没有调用 folder.close(true);。但是两个邮件服务器对使用相同代码的删除有不同的响应。

一件有趣的事情是，设置 DELETED 标志会从 Yahoo 以及 Gmail 帐户中的给定文件夹中删除邮件。只有 JavaMail 在 Yahoo 的情况下显示它们还活着。

是否有其他方法可以在不调用 folder.close(true); 的情况下删除消息？

谢谢

是的，请调用 EXPUNGE 或 UID EXPUNGE 。将邮件标记为已删除只是一个标记。要真正摆脱它们，您必须删除它们。
