有人可以建议我如何阻止从我的Linux服务器发送的所有电子邮件.
如果有帮助的话,我在Ubuntu 12.03 LTS上.

>查看其中一封垃圾邮件的标题.这就是你如何找到他们来自哪里.如果没有看到这些标题,我无法提供更多信息.
>清除队列中的垃圾邮件.如果您不关心仍在队列中的任何“真实”邮件,删除整个队列将是最快和最简单的.这是通过postqueue -d ALL完成的.如果您不想删除整个队列,请使用postqueue -p打印出队列内容.然后,对于您实际想要发送的每封邮件,查看该邮件的队列ID,并使用postsuper -H queue_ID将其从保留中删除.一旦完成(并复制了一些垃圾邮件的内容以供进一步分析),您可以通过运行postsuper -d ALL hold来清除保留队列中的剩余垃圾邮件.
>如果有,则需要关闭postfix.马上.在您弄清楚垃圾邮件的来源并确定您已将其停止之前,请勿重新启动它.有关于如何在 the postfix documentation保护后缀服务器的信息.如果您已经这样做但垃圾邮件仍然存在,则可能是通过某些Web服务或其他恶意软件.弄清楚这个问题超出了这个问题的范围.
>您的邮件服务器已列入黑名单.您需要通过例如设置邮件中继ISP服务器,或者您需要脱离黑名单.在 http://www.spamhaus.org/有关于此的信息. 总结
