MS Series can be hardware-based or software-based. Hardware-based servers are easy to install and maintain. After booting up, IT personnel just needs to configure the IP addresses and import accounts to get started. Software-based servers, on the other hand, require compliant hardware for deployment, providing greater flexibility. MS Series provides comprehensive mail protection, including antivirus engines; auditing and filtering management; complete logging, recording, backup, and restoration; a user-friendly management interface; and Webmail with a calendar and a cloud HDD.
