SmarterMail Free supports one domain with up to 10 mailboxes and has most of the features of SmarterMail Enterprise. Features NOT included in the Free Edition include: the ability to sync desktop and mobile clients using protocols such as MAPI/EWS or EAS, and the ability to use premium add-ons. The Free Edition is primarily used to give you an opportunity to try out SmarterMail before making a purchase decision. However, small companies can use it as a free, full-service email and collaboration server.
