Section 2. Investigation (分析)

The problem is that those reputed network computer declared our email domain server is spam and blacklist us. We found from the http://mxtoolbox.com, and it will come up the blacklist result which we require to apply for removing blacklist item one by one. However, Weexperience that those blacklist is very difficult to be completely removed. The actual situation is that we cannot guarantee our network without any spam and virus especially difficult for small SME without much investment on network security.

Even-though I submitted for removal, the result was that some were removed, but some others added, as below diagram.Maybe a period of time after removal, it put thedomain to blacklist again.It is a very annoying problem, and quite trouble.
