IceWarp

The company was founded in 2001 and its original product Merak Mail Server had been in development since 1998 as a mail server for Windows, later also released for Linux. The product was subsequently renamed IceWarp Mail Server.

During the 2010s, the product expanded beyond email into a broader collaboration platform, adding a browser-based client, mobile applications for iOS and Android, and web-based document editing. In 2015, IceWarp partnered with Collabora to fund and co-develop LibreOffice Online, a browser-based version of the open-source LibreOffice office suite.

In 2017, IceWarp acquired the Mirapoint Email Appliance business from Synchronoss Technologies.

The current product generation is marketed as IceWarp EPOS, which combined the platform's email, chat, conferencing, document, and file components under a single web-based interface.

IceWarp Mail Server is a mail server integrating all communication and collaboration features in one unified application. Available in cloud or for on-premises deployment, IceWarp is a tool to share and exchange all information and ideas online, offline or via mobile devices.
