MailSite SE is easy to install and operate. It has been designed with the nonprofessional administrator in mind. It does not require extensive training or advanced certification in order to install and operate. This means that you don't need to employ a full time administrator just to run your email system.

MailSite SE can be configured with spam and virus protection that block unwanted messages and infected files at the MailSite server, before they can get to users' desktops. This is the most effective and efficient way of protecting end users. All incoming messages are automatically scanned before they are accepted for delivery. Spam is scored and either blocked or passed to end users' personalized filters, while infected messages are immediately blocked. Both spam and virus definition files are automatically updated.
