sieve-generator

这是一个命令行界面，用于根据接收者电子邮件地址生成不同文件夹的.sieve电子邮件过滤器允许列表，通过JSON文件配置。我有一个捕获所有电子邮件域，并使用它自动化允许列表创建过程，每次使用新电子邮件时。（例如，将something@domain.com过滤到something文件夹）

安装

cargo install sieve-generator或下载二进制文件，仅在Linux上测试。

用法

假设我们有一个这样的JSON配置文件

{
    "domain.com": {
        "options": { // global options
            // if every folder should be a sub-folder of a domain named folder
            "domain-as-first-folder": false,
        },
        "Newsletter": {
            "Software": ["google", "facebook"],
            "Business": "wallstreet"
        },
        "Utilities": {
            "self": ["electricity"],
            "Grocery": {
                "localparts": "market",
                // if title or sender contains keyword then go to label
                // by default every labeled mail will not be marked read
                // even if silent is set
                "labels": {
                    "label": "keyword",
                    "label2": ["keyword2"]
                },
                "options": {
                    // the generic filter here will be grocery.secret and
                    // not utilities.grocery.secret
                    "orphan": true,
                    // mark all email of this folder as read
                    "silent": true,
                    // not generate generic filter for this folder
                    "generic": false
                }
            }
        }
    }
}

将生成一个.sieve过滤器允许列表，其中

• 它适用于发送到*@domain.com的所有电子邮件
• wallstreet@domain.com将被过滤到Newsletter父文件夹中的Business文件夹，依此类推。
• 使用self关键字设置具有子文件夹的父文件夹的过滤器（例如，Utilities）。
• 有简写过滤器（例如，Business文件夹）和全称过滤器（例如，Grocery），允许指定选项和标签规则。
• 为文件夹树中的每个生成一个通用过滤器，例如，newsletter.business.*@domain.com被过滤到Business文件夹。
• 默认情况下，未允许列表的所有邮件都将放入一个名为Unknown的文件夹中。
• Unknown是一个特殊文件夹，所有放入那里的邮件都将保持沉默，即使显式配置。

上面的JSON将产生

# @domain.com
if envelope :domain :is "to" "domain.com" {
    # Custom filters
    if envelope :localpart :matches "to" ["market"] {
        if header :contains ["from","subject"] ["keyword","keyword2"] {
            if header :contains ["from","subject"] ["keyword"] {
                fileinto "label";
            }
            if header :contains ["from","subject"] ["keyword2"] {
                fileinto "label2";
            }
        } else {
            addflag "\\Seen";
            fileinto "unread";
        }
        fileinto "Utilities";
        fileinto "Utilities/Grocery";
    } elsif envelope :localpart :matches "to" ["electricity"] {
        fileinto "Utilities";
    } elsif envelope :localpart :matches "to" ["google","facebook"] {
        fileinto "Newsletter";
        fileinto "Newsletter/Software";
    } elsif envelope :localpart :matches "to" ["wallstreet"] {
        fileinto "Newsletter";
        fileinto "Newsletter/Business";
    }
    # Generic filters
    elsif envelope :localpart :matches "to" ["utilities","utilities.*"] {
        fileinto "Utilities";
    } elsif envelope :localpart :matches "to" ["newsletter.software","newsletter.software.*"] {
        fileinto "Newsletter";
        fileinto "Newsletter/Software";
    } elsif envelope :localpart :matches "to" ["newsletter.business","newsletter.business.*"] {
        fileinto "Newsletter";
        fileinto "Newsletter/Business";
    } elsif envelope :localpart :matches "to" ["newsletter","newsletter.*"] {
        fileinto "Newsletter";
    } else {
        addflag "\\Seen";
        fileinto "Unknown";
    }
