Postfix服务器从本地发送垃圾邮件,难道是被入侵了?
前几日在Linode的VPS(Ubuntu 12.04TLS)上尝试着搭建了Postfix服务器(特别注意了不是open relay的)。
昨天被Linode通知我的vps发送垃圾邮件,
postqueue -p
发现postqueue中有多封莫名其妙的邮件,日志如下:

查看登陆日志,除了自己没有其他人登陆过。登陆IP都是自己的常用IP。
但是,这些垃圾邮件及感染是从localhost上发送的,而我自己确保没有做过类似的操作。
这个状况,是不是意味着我的VPS被入侵了呢?该怎么检测和解决呢?现在已经无法发出邮件了,被许多检查垃圾邮件的组织封锁IP了><...。
自己对于运维没有经验,现在不知道下一步怎么办了,请各位指点。多谢了!
