EasyDMARC Alternative: Why Teams Are Switching

EasyDMARC가 2023년 말부터 2024년 초 사이에 무료 플랜을 대폭 축소하고 가격을 인상하면서 SMB와 IT 팀 사용자들이 대안 도구를 찾고 있다. EasyDMARC는 ARC와 DANE/TLSA 같은 중요한 이메일 인증 프로토콜을 지원하지 않아 보안 측면에서 한계가 있다. 주요 대안으로는 DMARCguard, dmarcian, PowerDMARC가 있으며, DMARCguard는 가장 완전한 프로토콜 지원과 구체적인 문제 해결 가이드를 제공해 주목받고 있다. 가격과 프로토콜 지원, 데이터 마이그레이션 가능성 등을 고려해 조직에 맞는 도구 선택이 중요하다.

ARC chain analyzer: trace authentication through forwarders.

email forwarding breaks DMARC.

when a message is forwarded through a mailing list or university relay, the original SPF alignment is lost.

ARC (Authenticated Received Chain, RFC 8617) preserves the authentication results across hops.

I built it because forwarding is the #1 source of false-positive DMARC failures.

named senders changed everything.

every platform shows you IPs.

I wanted to see names. Mailchimp, Google Workspace, Salesforce, SendGrid. not CIDR blocks.

so I built a sender identification system.

it maps IPs to known ESPs and cloud providers automatically.

when you look at your DMARC report in DMARCguard, you see "Mailchimp sent 4,200 messages, 98% aligned". not a wall of numbers.

MTA-STS: forcing TLS on your inbound mail.

SMTP was designed without encryption.

STARTTLS added opportunistic encryption, but it's trivially downgraded by a MITM stripping the STARTTLS response.

MTA-STS fixes this.

combined with TLS-RPT , you get reports when senders fail to establish TLS.

without TLS-RPT, MTA-STS enforcement is blind... you won't know when legitimate mail is being rejected due to certificate issues.
