最近，有人将我的服务器用作开放中继，大量垃圾邮件通过我的服务器发送。从那时起，我就停止了这种做法，但我的邮件日志却因这种类型的日志而大幅增长。

我仍然无法发送或接收邮件。我已保护我的联系表并尝试阻止一些违规 IP 地址。今天早上我发现了新的 IP 地址。
我也尝试过http://www.howtoforge.com/how-to-log-emails-sent-with-phps-mail-function-to-detect-form-spam但日志文件没有附加。我真的很沮丧，还没有找到解决办法。有人能告诉我可以采取哪些步骤来解决这个问题吗？拜托。另外，我的邮件队列已经增长了很多。我应该采取什么步骤来查找服务器上的恶意脚本？为什么发送邮件不起作用？
问我任何日志，我会将它们输出到这里以尝试解决这个问题。
我正在使用 centos、nginx（作为代理）、varnish、apache2 for php 和 postfix。谢谢。
答案1
对不起，肖恩。
但 Shane 的建议是错误的。现在你拒绝任何来自外部的连接！这一定是smtpd_recipient_restrictions = permit_mynetworks, reject
之前的配置不是问题。如果您不设置 Shane 错过的参数，Postfix 会隐式设置它们。不是，smtpd_client_restrictions但是smtpd_recipient_restrictions这些具有相同的效果。我测试了给定的配置，并且您没有打开中继。
顺便说一下，给出的日志没有显示任何来自外部的可疑活动。只有正常的连接和正常的 REJECTS。
您只能看到外发邮件。不管它们来自哪里，因为您没有显示日志，例如 ID 为 DC8BD1641F1 的邮件来自哪里。
