Postfix发送垃圾邮件到本地电子邮件地址没有身份validation

运行在Centos 6.4上。 过去两周，我一直在接收来自位于服务器上的其他电子邮件帐户的电子邮件。 [email protected]发送到[email protected]和[email protected]发送到[email protected]。 他们都包含一个zip文件。 电子邮件最近开始从[email protected]进来（网站甚至没有子域）。

我相当密切地监视服务器，并没有看到任何违反FTP，SSH或PHP代码。

这些电子邮件似乎来自土耳其和其他中东地区。 没有垃圾邮件被送出服务器，他们只被发送和本地交付。

我以为我已经设置为validation所有用户，但它不authentication，仍然发送。 有人可以阐明如何做或改变？

• postfix +虚拟用户（db）：添加一个不可回收的地址
• Postfix将不会从窗体发送PHP邮件（）函数
• iRedMail：Telnet的sendmail通过postfix可能没有邮箱，而没有login的别名
• 用postfix限制发件人和收件人
• Postfix邮件服务器拒绝来自外部邮件服务器的连接

这里是postfix / main.cf文件的一些内容。
