Lotus Notes 代理 - 删除嵌入式图像？

Question

我有一个多年前共享的代理，它获取附件，将它们保存到我的硬盘驱动器，然后从电子邮件中删除它们。我用它来保留我的电子邮件一段时间，但保持在我的公司邮箱配额之下。我收到很多附件。

我现在发现许多剩余的大型电子邮件都嵌入了图像，而不是“附加文件”。任何人都可以共享一个实际上能够使用嵌入图像执行相同操作（保存到硬盘驱动器、从电子邮件中删除）的脚本吗？

FWIW，这是我用于分离附件的代理。原作者的道具，不知道是谁。

这对于脚本来说是非常有问题的，因为它目前处于 MIME 编码图像不会使用 EmbeddedObjects 属性显示为任何类型的附件。

如果图像作为 MIME 消息的一部分内嵌存储，Notes 客户端会将它们转换为附件以供查看，但只能作为 MIME 消息的一部分以编程方式访问。应该可以通过图像编码（使用 MIMEEntity 类）获取多部分 MIME 消息的正确部分，将其流式传输到磁盘并重建原始文件，然后删除代表它的 MIMEEntity（并采取增加空间）。
