发送到台湾邮件总是退信,提示说
The simplest and most effective way to stop this is to configure your NAT to prohibit connections to the Internet on port 25 except from real mail servers. Not only does this stop all of these viruses and spams dead in their tracks, the NAT logs will immediately tell you the LAN address of the infected machine.
该怎么解决.非常感谢,请大家关注一下. |
