Email Security delivery impacted by Spamhaus listing

🤖 AI Summary

Cloudflareの記事「Email Security delivery impacted by Spamhaus listing」を日本語で要約します。

8月12日、Spamhausによってリスト化されたIPアドレスによるメールセキュリティ配信障害が発生しました。以下に主な内容をまとめます:

- 8月12日16時48分:Spamhausでリスト化されていた全てのIPがクリーンになったことを確認。ダウンストリームシステムへの変更の拡散状況をモニタリング中。
- 8月12日17時23分:障害は解決しました。

主要な影響:
- O365を使用する顧客は、必要事項が完了していない場合にのみ影響を受ける可能性がある。設定を確認し、全送出IPを含めることを推奨。
- 134.195.26.0/23ブロックのIPからのメールが拒否されるという問題を発見。このIPブロックはすべてのダウンストリームシステムで許可すべきであり、Cloudflare Email Securityがメールの元発信者とみなされないようにするため、Spamhausフィルタリングはダウンストリームシステムで無効化することを推奨。

障害期間:8月12日15時04分〜17時23分

Cloudflare: https://www.cloudflarestatus.com/incidents/fdyjr0t87mrb

Aug 12, 17:23 UTC
Resolved - This incident is now resolved.

Aug 12, 16:48 UTC
Monitoring - All IPs previously listed by Spamhaus are now clean. Monitoring the propagation of that change to downstream systems.

Aug 12, 16:30 UTC
Investigating - We are continuing to investigate this issue. Customers using O365 will be impacted only if they have not completed the required setup. Please check your setup and ensure the connector includes all egress IPs: https://developers.cloudflare.com/cloudflare-one/email-security/setup/pre-delivery-deployment/prerequisites/m365-email-security-mx/#2-configure-enhanced-filtering

Aug 12, 15:07 UTC
Investigating - We are continuing to investigate this issue.

Aug 12, 15:04 UTC
Investigating - We are currently investigating an issue where customers that use Spamhaus for additional filtering of email downstream from the Cloudflare Email Security service are rejecting emails from IPs in the 134.195.26.0/23 block. This IP block should be allowed for all customer downstream systems to avoid treating the Email Security service as an originator of mail. We recommend all Cloudflare Email Security customers disable Spamhaus filtering in downstream systems.
