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);
});
