发邮件退信，我以经把@idt-dichtungen.de 加入了白名单及信任主机当中了，大家帮我分析一下是什么原因导致退信呢？

551 ：用户非本地，请尝试＜forward-path＞

　　这个应答意味着接收SMTP知道用户的邮箱在另外的主机上，并意味着使用了正确的转发路径。注意请注意，主机或者用户，或者它们两者是不同的。接收方拒绝接收此用户的信件，发送者必须根据提供的信息重新发送或者向原发送者返回错误信息。下例显示了这些响应的应用。

　　转发的例子
　　S: RCPT TO:＜Postel@USC-ISI.ARPA＞
　　R: 251 User not local; will forward to ＜Postel@USC-ISIF.ARPA＞
　　或者
　　S: RCPT TO:＜Paul@USC-ISIB.ARPA＞
　　R: 551 User not local; please try ＜Mockapetris@USC-ISIF.ARPA＞
