如何匹配procmail中邮件正文中的任何空格？

Question

I tried to use such rule: 我试图使用这样的规则：

:0 B
* Something[[:space:]]+whatever

but it doesn't work. 但这不起作用。

When I change [[:space:]] to literal space character: 当我将[[：space：]]更改为文字空格字符时：

:0 B
* Something +whatever

it works. 有用。

It also works in case of: 在以下情况下也可以使用：

:0 B
* Something[ ]+whatever

I must be doing something wrong, but can't really find it. 我一定做错了，但是找不到。 Any hints? 有什么提示吗？

What about just adding the white space characters in a class you want to match: 仅在要匹配的类中添加空格字符怎么办：

[ \t\r\n]

matches a space, tab, carriage return and line feed. 与空格，制表符，回车符和换行符匹配。

There are of course more white space chars, but these are the most commonly used. 当然，还有更多的空白字符，但是这些是最常用的。
