Procmail自动创建新文件夹以存储来自新发件人的电子邮件 [英] Procmail to automatically make new folders to store emails from new senders

问题描述

我正在学习如何使用procmail，但是到现在为止，我什至不确定它是否是我要执行的操作的正确工具.

I am learning how to use procmail but at this point, I am not even sure it's the right tool for what I am trying to do.

到目前为止，我已经设法获取fetchmail来从Google IMAP帐户检索电子邮件，并获取procmail来将这些电子邮件过滤到我先前创建的本地文件夹中.

So far, I have managed to get fetchmail to retrieve emails from a Google IMAP account and procmail to filter those emails into local folders I had previously created.

我想知道，是否有一种方法可以使procmail在检索来自新发件人的电子邮件时自动在本地创建一个新文件夹，并将该电子邮件存储到该文件夹​​中.

I am wondering though whether there is a way to get procmail to automatically create a new folder locally when an email from a new sender is being retrieved and to store that email into that folder.

到目前为止，我只发现了一个网站，该网站描述了procmail可能会自动创建用于邮件列表的文件夹的方法，但是使用我不知道其含义的字符却使方法变得有些疯狂，而且procproc官方网站似乎无法访问.

So far, I have only found a website that describes the possibility of procmail creating automatically folders for mailing lists, but the recipe is something crazy using characters which I have no idea the meaning of, furthermore the official procmail website seems unreachable.

请您能帮忙吗?谢谢.

推荐答案

目前尚不清楚您希望该文件夹被调用的内容以及所使用的邮箱格式；但是假设使用发件人的电子邮件终端命名的maildir文件夹，请尝试

It's not clear what you expect the folder to be called, and what mailbox format you're using; but assuming maildir folders named by the sender's email terminus, try

Who=`formail -rtzxTo:`
:0
* ? mkdir -p "$Who"
$Who/

对于mbox文件夹，您根本不需要目录检查，因为该文件夹只是一个文本文件，您可以从文件夹名称中删除最后的斜杠. Mbox需要锁定，因此请在零后面添加第二个冒号.

For an mbox folder, you don't need the directory check at all, because the folder is just a single text file, and you'd drop the final slash from the folder name. Mbox needs locking, so add a second colon after the zero.

Who=`formail -rtzxTo:`
:0:
$Who

获取formail来创建回复，然后提取所生成的回复的To:标头是一种标准的方法，但这种方法不太明显，它仅获取输入消息发件人的电子邮件终端.

Getting formail to create a reply and then extracting the To: header of the generated reply is a standard but slightly unobvious way to obtain just the email terminus for the sender of the input message.

如果dir尚不存在，则创建dir，否则为无害操作.

The shell snippet mkdir -p dir creates dir if it doesn't already exist, and is a harmless no-op otherwise.
