Mail Server and Collaboration solution for Linux and Windows. Full-featured and cost-effective alternative to Microsoft Exchange. IceWarp sponsored this project with a license for IceWarp Mail server.
IceWarp is just more than an a mail server. We prefer IceWarp for the flexibility of options you can have. We used several other mail server software that can't compete with IceWarp.
Current version: IceWarp Server Version 12.1.1
