smtp;550 访问被拒绝 - HELO 名称无效(请参阅 RFC2821 4.1.1.1) [英] smtp;550 Access denied - Invalid HELO name (See RFC2821 4.1.1.1)
问题描述
我正在运行 Windows Server 2008 R2，但收到来自几个域的 smtp 邮件被拒绝.
I'm running Windows server 2008 R2 but am getting smtp mail rejected from a few domains.
为了测试它，我将一个文本文件放入 C:inetpubmailrootPickup 目录，如下所示:
To test it I'm dropping a text file into C:inetpubmailrootPickup directory, with something like this:
From: my@emailaddress.com
To: someone@somewhere.com
Subject: testing
This is a test
它将发送到某些域，但有些正在返回:
It will send to some domains, but some are returning:
Reporting-MTA: dns;DEDICAT-93I3U5A
Received-From-MTA: dns;DEDICAT-93I3U5A
Arrival-Date: Wed, 8 Aug 2012 12:50:58 +0100
Final-Recipient: rfc822;someone@somewhere.com
Action: failed
Status: 5.5.0
Diagnostic-Code: smtp;550 Access denied - Invalid HELO name (See RFC2821 4.1.1.1)
我知道这可能与服务器 (IIS 7.5) 上的 smtp 设置有关.谁能给我一些关于从哪里开始的建议?
I understand this could be something to do with the smtp setup on the server (IIS 7.5). Can anybody give me some advice as to where to start please?
谢谢，
安迪.
推荐答案
一些 SMTP 服务器要求您使用 HELO 命令发送一个有效的主机名，该主机名也与请求源自的 IP 地址的反向 DNS 相同.
Some SMTP servers require you to send a valid host name with the HELO command that also is the same as the reverse DNS of the IP address the request originates from.
您可以通过旧的 IIS6 管理控制台配置 IIS SMTP 服务器使用的主机名.为此，请选择 SMTP 服务器，右键单击并选择 Properties，转到选项卡 Delivery，然后单击按钮 Advanced.
You can configure the host name the IIS SMTP Server uses through the old IIS6 Management Console. To do so, select the SMTP Server, right click and select Properties, go to the tab Delivery and then click on the button Advanced.
您的 IP 地址的反向 DNS 通常由您的 ISP 控制.
The reverse DNS for your IP address is usually controlled by your ISP.
