我有几个一般性的问题。我在 Google 上搜索过这些问题，无论是教程还是博客，都没有找到答案。
所有这些都与邮件日志有关。每天大约同一时间我们的网站都会瘫痪。目前我们正在调查可能的电子邮件劫持事件。
我有两个账户似乎很突出。这里提到的一个仅供内部使用，从未登录过，也从未发送过任何邮件。从来没有。但是，如果我没有看错，这个日志看起来好像有人在使用。我们的邮件评级已降至“差”状态。
昨天我进入了服务器的 ispconfig 并删除了电子邮件地址，但今天的日志仍然显示它在运行。不知道接下来该怎么办。

答案1
为了帮助回答这个问题，您需要发布其中一条有问题的消息的完整日志。为此，请在日志中 grep 消息 ID（消息 ID 是进程名称后的十六进制数字，在您的日志片段中，第一个是：189042213CB4）。
这将为您提供 Postfix 处理消息的完整详细信息。该输出的第一行应以“client=”结尾。这是消息来源的 IP 地址。如果是内部地址，请检查该机器上发生了什么；如果是外部地址，则可能是中继问题；最后，如果是本地主机，那么正如 Zoredache 所建议的那样，您的邮件服务器可能已受到威胁。
