Cloudflare Email security 新增按内容阻止邮件的规则
Email security - Block emails by content with blocked content rules
Cloudflare Email security now lets administrators write their own content-based blocking rules. A new Blocked content area under Policies & rules lets you define a plaintext string or a regular expression, choose whether to scan the message subject, body, or both, and automatically block any message that matches.
Cloudflare 电子邮件安全现在允许管理员编写自己的基于内容的阻止规则。在“策略与规则”下新增的“阻止内容”区域中，您可以定义纯文本字符串或正则表达式，选择是否扫描邮件主题、正文或两者，并自动阻止任何匹配的邮件。
- Create rules using either plaintext matches or regular expressions — useful for blocking targeted phishing campaigns, known-bad phrases, or content patterns unique to your organization.
- Choose the search location for each rule: subject, body, or subject and body.
- Use the built-in regular expression checker to validate your pattern against sample text before saving, so you can confirm the rule matches what you expect and avoid false positives.
- Matching messages are marked with a malicious disposition and prevented from reaching users' inboxes.
- 使用纯文本匹配或正则表达式创建规则——这对于阻止定向钓鱼活动、已知恶意短语或您组织特有的内容模式非常有用。
- 为每条规则选择搜索位置：主题、正文或主题和正文。
- 使用内置的正则表达式检查器，在保存前根据示例文本验证您的模式，以便确认规则符合预期并避免误报。
- 匹配的邮件会被标记为恶意处置，并阻止其到达用户的收件箱。
