我最近被用作开放中继，大量垃圾邮件通过我的服务器发送。 我从那以后停止了它，但是我的邮件日志随着这种types的日志大大增加了。

我也试过http://www.howtoforge.com/how-to-log-emails-sent-with-phps-mail-function-to-detect-form-spam，但是日志文件没有附加。 我真的很沮丧，还没有find解决scheme。 有人能指出我可以采取哪些措施来解决问题。 请。 另外，我的邮件队列也大大增加了。 我会采取哪些步骤来查找我的服务器上的任何恶意脚本？ 为什么不发送邮件工作？
问我任何日志，我会在这里输出它们来试图解决这个问题。
我使用的是centos，nginx（作为代理），varnish，PHP的apache2和后缀。 谢谢。
对不起肖恩
但是谢恩的推荐是错误的。 现在你拒绝任何来自外部的连接！ 它必须是smtpd_recipient_restrictions = permit_mynetworks, reject
以前的configuration不是问题。 如果你没有设置参数，那么Shane的参数将由Postfix隐式设置。 不是smtpd_client_restrictions但smtpd_recipient_restrictions但这些具有相同的效果。 我testing了给定的configuration，并且没有开放中继。
顺便说一下，给定的日志不会从外面显示任何可疑的活动。 只有连接不坏和拒绝哪个是好的。
你只看到传出的邮件。 无论他们来自哪里，因为你没有显示日志如何，例如，DC8BD1641F1的邮件来自。
