关于Spam Scanner

Spam Scanner是一款功能强大的反垃圾邮件、电子邮件过滤和网络钓鱼防御服务平台。Spam Scanner也是SpamAssassin、rspamd、SpamTitan等产品的最佳替代选择。

我们的目标是建立和利用一个可扩展、性能好、简单、易于维护、功能强大的API，用于我们的转发电子邮件服务，以限制垃圾邮件，并提供其他措施来防止网络犯罪分子对我们的用户展开攻击。

最初我们尝试使用SpamAssassin，后来评估了rspamd，但最终我们发现所有现有的解决方案都非常复杂，缺少所需的功能或文档，配置起来也比较麻烦，技术壁垒较高，从其他角度来说也限制了平台的可扩展性。

对我们来说，我们重视隐私以及数据和用户的安全性——特别是我们对存储任何类型的日志或元数据都有“零容忍政策”。这些解决方案中没有一个符合这一隐私政策（没有删除基本的垃圾邮件检测功能），因此Spam Scanner便应运而生。

工具安装-NPM安装

npm install spamscanner

工具使用

const fs = require('fs');

const path = require('path');

 

const SpamScanner = require('spamscanner');

 

const scanner = new SpamScanner();

 

//

// NOTE: The `source` argument is the full raw email to be scanned

// and you can pass it as String, Buffer, or valid file path

//

const source = fs.readFileSync(

  path.join(__dirname, 'test', 'fixtures', 'spam.eml')

);

 

// async/await usage

(async () => {

  try {

    const scan = await scanner.scan(source);

    console.log('scan', scan);

  } catch (err) {

    console.error(err);

  }

});

 

// then/catch usage

scanner

  .scan(source)

  .then(scan => console.log('scan', scan))

  .catch(console.error);

 

// callback usage

if (err) return console.error(err);

scanner.scan(source, (err, scan) => {

  if (err) return console.error(err);

  console.log('scan', scan);

});
