DMARC 报告分析
分析 DMARC 汇总报告,了解邮件认证表现
DMARC aggregate reports provide insights into email authentication results, helping identify legitimate sources and potential threats. Upload XML or paste report data for analysis.
DMARC 报告数据
粘贴 DMARC 汇总报告 XML 内容或上传报告文件
Tip: DMARC reports are typically sent as XML attachments by email providers
准备好分析 DMARC 报告
Paste DMARC aggregate report XML content above to analyze authentication performance.
你将获得:
- 认证通过/失败率
- 主要发送 IP 地址
- 消息处置分析
- 策略合规洞察
什么是 DMARC?
DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email authentication protocol that builds upon SPF and DKIM to provide domain owners with the ability to protect their domain from unauthorized use, commonly known as email spoofing.
核心组成部分:
- 策略(p):定义邮件认证失败时要采取的操作(none、quarantine、reject)
- 子域策略(sp):与主域不同的子域策略
- 对齐(adkim/aspf):DKIM 和 SPF 对齐的执行严格程度(宽松或严格)
- 百分比(pct):策略适用的邮件百分比
DMARC 的工作原理:
- 邮件发送并由收件人的邮件服务器接收
- 服务器检查 SPF 和 DKIM 认证
- 根据认证结果评估 DMARC 策略
- 根据策略采取操作(none、quarantine 或 reject)
- 生成报告并发送给域名所有者
