帮助！哈哈。我最近是个傻瓜，把我的服务器搞坏了。我有一个邮件服务器在服务器上运行。在我的新服务器上，我试图重新设置它，但无法让它工作。我的配置和以前几乎一模一样。一切都正常，只是我无法从外部来源接收电子邮件。我可以发送电子邮件，我可以从我自己的主机接收表单，只是不能从另一个主机接收。我已经搜索了几天才找到我所在的地方。我只想放弃。
编辑：补充一下，我还可以通过 Outlook 进行外部连接以接收和发送邮件。如果我通过 Outlook 向自己发送电子邮件，则一切正常。这不是我的防火墙或 MX 记录的问题。
我尝试从外部来源发送电子邮件时收到的错误是
远程服务器返回“554 5.7.1：收件人地址被拒绝：访问被拒绝”
编辑：还发现此错误：
