Mail Filtering Service (Score 1)

My company has used email filtering services from MXLogic for years. I am sure that there are other equally competent service companies that you can compare if interested. This service allows staff to perform revenue - generating work and not fool around with managing spam and so it is very cost effective for us. The service gives each user a console to manage filtering, malware detection and so on. The licensing is by user. Good luck with your research.
