我们有一个内部 MS Exchange 2016 服务器。几年来它一直运行良好。这种情况越来越频繁地发生。用户收到回扣,称电子邮件无法送达。一段时间以来系统没有任何变化,所以这个错误像某种配置错误一样弹出来非常有趣。我注意到这种情况主要发生在 gmail 和 comcast 上,但也有少数来自其他域。
我想知道在哪里可以找到定义为 127.0.0.1 的 SMTP 服务器。
谢谢,

如果您在服务器上使用 avast,则需要禁用服务器上的垃圾邮件防护和邮件防护组件。显然它们仅供工作站使用。您可以保留“Exchange”防护以继续保护您的电子邮件服务器。

我不知道该如何回答您的问题,但与 Avast 防火墙一样,Mail Shield 和反垃圾邮件组件都只设计用于工作站,而不是邮件服务器。我听说我们的开发/生产团队正在研究一种永久性解决方案,如果 Avast 安装检测到服务器上的 Exchange,该解决方案将自动删除这些组件。
