    Ease: 4 Stars. It is very easy to configure and use, but could use much more documentation explaining the features and their implications. Features: 3 Stars. Whilst most of the features are excellent and deserve 5 stars, the system lacks the most crucial of features and that is the white/blacklisting of IP addresses on the local server level rather than only depending on the RBL services. The white/blacklisting of email addresses and domain names is ineffective and could work against you. Design: 4 Stars. I would have given 5 stars, but the Ease and Features ratings naturally did not allow me to do so. Support: 5 Stars. Support is amazing. The blog is full of useful information and the developer invests a lot of time in answering questions and keeping the system updated. If there were an option for 6 stars, I would have chosen that one. Overall, I'm very happy with the system and I look forward to seeing it evolve more over time.
