我已经使用 Postfix 设置了 Mailman 3 服务器。我已经将 Postfix 配置为使用 OpenDKIM 添加 DKIM 标头，并且从该服务器向 Microsoft 托管的电子邮件地址发送的测试电子邮件表明 DKIM 正常：
Authentication-Results: spf=pass (sender IP is 1.2.3.4)
smtp.mailfrom=mmserver.org; destination.org; dkim=test (signature was
verified) header.d=mmserver.org;destination.org; dmarc=bestguesspass
action=none header.from=mmserver.org;compauth=pass reason=109
（域名和 IP 地址已编辑/更改）
使用 Mailman 时，除了 DKIM 之外还使用了 ARC，我不确定情况是否如此仍然正常工作。将测试电子邮件发送到 Mailman 列表，然后发送到相同的 Microsoft 托管电子邮件地址，结果将产生以下标头：

MIME-Version: 1.0
这似乎表明一个 DKIM 片段通过（签名已验证），但另一个 DKIM 片段失败（签名未验证）。这就是为什么 arc 总体上被标记为失败的原因吗？
我一直在努力弄清哪里可能配置错误，导致 DKIM 无法持续工作。如能提供任何帮助，我将不胜感激 :)
编辑后包含 Mailman 生成的电子邮件的完整标题。
此外，在 Mailman 列表中，有人建议从 Mailman 的 ARC 处理程序切换到 Postfix 的邮件过滤器。我已经开始研究 OpenARC，但文档很少。
答案1
DKIM/ARC 在我的 Mailman 服务器上运行正常吗？
不i=2，如果你之后的第一个 ARC 验证者 ( i=1) 声称链子断了（cv=fail）则表示有些部分没有正常工作。
由于标题的顺序，我几乎可以肯定你是密封前签署。
所有消息修改（包括添加 DKIM-Signature 标头字段）必须在密封之前执行。-- RFC8617：认证接收链 (ARC) 协议
根据所涉及的软件以及它们通过哪个接口集成到 Postfix（SMTP、milter、filter、policyd 等），遵守 ARC 协议描述的需求可能或多或少容易。这可能涉及重新排序 Postfix 配置中的条目，例如smtpd_milters。
我愿意不是知道这是否能解决你的问题。
我还是建议让一些非 Microsoft 方验证您的 DKIM 和 ARC 印章。文中提到的身份验证结果 ( dmarc=bestguesspass, dkim=test) 定义不明确，而且我见过 Microsoft 偏离普遍预期，甚至在收到时破坏了完全正确的 DKIM 签名，然后验证失败。
