Operating System IceWarp Mail Server is a multi-platform software and runs under many popular systems, as a daemon under Linux, as a service with modern Windows Server and Workstation, as an application under legacy Windows versions. This allows to leverage your existing OS licenses, or migrate to opensource to minimize investment and maximize server security.
Mail server engine is extremely resource aware and will run even on fairly modest hardware. Exact requirements are dependent on services traffic, user activity, settings of resource intensive features, number of add-on modules and communication usage patterns. This is especially true for dimensioning the disk storage capacity. If you plan to have thousands of users or expect heavy traffic, consider a dual-CPU system, Xeon processor or better, at least 1GB RAM and fast disk sub-system (SerialATA, SCSI). RAID is beneficial only if you require top data integrity or if configured to maximize disk I/O speed. External fileserver for data storage and backup is recommended for ISP-class installations.
