Windows or Linux
SmarterMail is the only cross-platform email and collaboration server that offers Microsoft Exchange level features and functionality -- without the need to install any additional custom software -- for Windows Server or Linux administrators. SmarterTools has also created a Docker version of SmarterMail for fast, efficient, and secure installation and configuration.
Any Email Client on Any OS
With support for all major email protocols, including IMAP, POP, EAS, EWS, WebDav, and MAPI, you have your choice of desktop or mobile client, regardless of your operating system. This includes Outlook for Windows or MacOS, Apple Mail, Samsung Mail, eM Client, Thunderbird, Gmail, Spark, Mailbird, and countless others!
In addition, SmarterMail is the only email server on the market, outside of Exchange, that offers native support for MAPI on Windows AND Linux. Other products offer Outlook plug-ins that simply mimic Exchange features or require custom email clients that offer similar features to Outlook. Support for MAPI, at the server level, makes SmarterMail the perfect alternative to Microsoft Exchange.


Industry Standard Email Security
Just add code
SmarterMail comes equipped with several email security features that are available without spending more money or adding third-party software. This includes industry standard spam filtering as well as enterprise-level antivirus. Additionally, we offer enterprise-level solutions such as Message Sniffer that can be integrated seamlessly.
Complete Mobile Integration
For those who prefer using email clients, calendaring and notes apps, and more on their mobile devices, SmarterMail seamlessly integrates with whatever you want to use. With support for Microsoft Exchange ActiveSync, your choice of mobile client or app, on iOS or Android, is practically limitless: Outlook Mobile, iOS Mail, Gmail, Samsung Mail, Blue Mail, Spark and more!
