SmarterMail Edition Explanation

Enterprise Edition

SmarterMail Enterprise has everything in the Professional Edition plus additional tools and features a business needs to bring an entire organization together. With the MAPI & EWS and EAS add-ons, SmarterMail Enterprise is truly a complete and affordable alternative to Microsoft Exchange. It's perfect for businesses looking for enterprise features, web hosting companies, ISPs and other service providers who want to offer a collaborative messaging platform. Some additional features that set Enterprise apart from Professional include:

  • Online Meetings
  • Live chat
  • Failover functionality
  • Ability to mark a domain as hosted externally
  • LDAP support
  • Active directory authentication
  • Email and chat archiving for SOX, HIPAA or other regulatory requirements
  • The ability to purchase and integrate one, or both, of the following licensed add-ons:
    • EAS for mobile (e.g., Outlook Mobile) synchronization
    • MAPI & EWS for Microsoft Outlook 2016 and above on Windows (MAPI), plus Apple desktop client synchronization (Outlook for Mac, Apple Mail) and eM Client on Windows (EWS).

SmarterMail Professional

SmarterMail Professional is a complete and feature-rich mail server. It offers the essentials: email, calendaring, contact lists, tasks and notes and the ability to share and collaborate on all of these features. It's the ideal solution for a business or organization that focuses on using primarily webmail for their day-to-day operations and includes the ability to sync mobile and desktop clients using IMAP, POP, CalDAV and CardDAV. SmarterMail Professional is a great solution for a number of small businesses or for individual users.

SmarterMail Free

SmarterMail Free contains much of the same functionality as SmarterMail Enterprise, but is limited to one domain with up to 10 users. This is to give you an opportunity to try all the features out before making a decision on what product to purchase.
