Question

我有一个从我的Gmail下载邮件的程序，我选择了单选按钮：为所有邮件启用POP（即使已经下载的邮件）

下载邮件后，我的Gmail会将上述状态更改为：自当前日期以来抵达的所有邮件都启用了POP

我没有实际更改单选按钮，但它接口就像它自动设置它只下载新邮件。

我需要我的窗户一直向下装载所有的时间。

如何在我的代码中设置Gmails必须始终启用所有下载？我不得不每次都选择单选按钮。

您不需要重新启用单选按钮，当pop客户端下载邮件时，其他pop客户端无法查看。通过使用最近的模式，前景如何。

尝试这不是你的所有邮件，而是过去30天。

只需将 recent> 添加到您的用户名，例如最近：Me@gmail.com。

最近模式获取最近30天的邮件，无论邮件是否已经发送到另一个POP1客户端。
