It is very easy for me using it as my personal mail server because I'm not required too many skills or knowledge of computer security. If you're looking at an easier way than learning about your own antivirus software then this may be right up your alley! Not really anything i dislike but if there was maybe more features available? Maybe like having multiple servers hosted with one account so its less hassle when changing out mailservers? But other than that - great product!! Easy management of emails through different domains/servers without needing any real technical skill set.
