SMTP错误554 [英] SMTP error 554

问题描述

我使用MDaemon作为邮件服务器，最后几天我收到从其中一台机器发送的电子邮件的错误554消息不符合标准。有什么想法可能造成的？其他机器工作正常。

I'm using MDaemon as out mail server and the last days I get an error "554 Message does not conform to standards" for emails sent from one of the machines. Any idea what may be causing it? Other machines work fine.

推荐答案

SMTP错误554是更模糊的错误代码之一，但通常是由接收服务器看到在From或To标题中它不喜欢的东西。这可能是由垃圾邮件陷阱识别您的计算机作为中继，或作为不信任从您的域发送邮件的机器。

SMTP error 554 is one of the more vague error codes, but is typically caused by the receiving server seeing something in the From or To headers that it doesn't like. This can be caused by a spam trap identifying your machine as a relay, or as a machine not trusted to send mail from your domain.

最近遇到这个问题在我们的阵列中添加一个新的服务器，我们通过确保我们有正确的反向DNS查找设置。

We ran into this problem recently when adding a new server to our array, and we fixed it by making sure that we had the correct reverse DNS lookup set up.
