我有一个用于发送电子邮件的中继服务器。我使用 dkim 签署出站电子邮件。当我使用 telnet 发送邮件时，gmail 日志如下所示：
Received-SPF: pass (google.com: domain of [email protected] designates X.X.X.X as permitted sender) client-ip=X.X.X.X;
Authentication-Results: mx.google.com;
dkim=pass [email protected];
spf=pass (google.com: domain of [email protected] designates X.X.X.X as permitted sender) smtp.mailfrom=user@test;
当我使用 mailx 客户端发送到同一个中继服务器时，我得到以下信息：
Received-SPF: pass (google.com: domain of [email protected] designates X.X.X.X as permitted sender) client-ip=X.X.X.X;
Authentication-Results: mx.google.com;
dkim=fail [email protected];
spf=pass (google.com: domain of [email protected] designates X.X.X.X as permitted sender) [email protected];
我很困惑为什么它会返回不同的结果。我也从同一个服务器发送电子邮件。雅虎邮箱也出现了这个问题。
