Anti-spam settings can be set per-user. Grey-listing is supported. Mal-ware is automatically detected and infected client PCs are automatically black-listed. POP load balancing is done. SMTP AUTH is supported. There is a Web-based management interface. Spam blocking is done by on-the-fly connection behavior analysis. It handles up to 10,000 concurrent SMTP connections.

    Release Notes: Cloud synchronization between multiple machines has been added. This feature includes auto-discovery and replication of grey-listing, access, account, and spam detection database records. This allows Proto Balance Mail to be installed in a HA (High Availability) deployment pattern with multiple Proto Balance Mail machines each assigned their own MX record. This allows easy scalability of up to 1,000,000 mailboxes in a "no-single-point-of-failure" model. Other features include demo configuration, a watchdog-process feature, and improvements to the XML management interface.
