451 尝试验证来自某些外部联系人的 RCPT 错误时超时

  • 772

两家公司的外部联系人报告他们发送给我们的消息返回以下消息：

451 尝试验证域的 RCPT [email protected] 超时

其中一家公司是一个非常大的国际组织，所以我怀疑问题一定是在他们头上。

我理解此消息通常意味着我的服务器在响应来自其他服务器的 RCPT 消息之前断开连接。

我有一个 Exchange 2007 服务器，第一批报告该问题的人（以及我能够从中获得错误消息副本的人）正在运行 Lotus Domino（我不记得我的 Domino 支持日子）。

我们还通过 DNSMadeEasy 使用电子邮件备份服务来处理我们所有传入的消息，这样，如果我们的服务器在一段时间内与互联网失去联系，DNSMadeEasy 将接收所有消息并对其进行排队，并在建立连接后将消息传递到我们。

我做过的事情：

  • 使用我的个人外部帐户测试了内部/外部电子邮件通信，没有任何问题。
  • 已验证我没有在 Exchange 中配置反垃圾邮件黑名单。
  • 检查了我的 McAfee Groupshield 日志并确认它没有拒绝来自这些发件人的任何邮件。

我从这里去哪里？

这是 Lotus Notes 的完整输出（适当模糊），关于它认为的问题是什么（对于第一部分中的墙'o 文本感到抱歉，我无法让这些行正常流动）：

    最好的方法是与远程公司一起解决该问题。他们可以检查那里的日志，而您可以检查您的日志。如果您的服务器确实导致超时，他们可能会像此处提到的那样快速调整那里的 MailTimeout 值。因此，如果此设置为 4 小时（目前看起来），他们可以将其更改为 8 小时。他们还可以在那边启用SMTP 调试以检查发生了什么。
