SonicWALL Antispam
Port 2599 is utilized by SonicWALL's Antispam service for communication between the Remote Analyzer (RA) and the Control Center (CC). This dedicated connection enables real-time transfer of spam analysis data, updates, and coordination commands, facilitating effective centralized spam filtering across distributed email environments..
Purpose: Port 2599 is employed by SonicWALL's Antispam solution to transmit data between distributed Remote Analyzers and a central Control Center. This architecture allows multiple points of email flow analysis to coordinate, sharing threat intelligence and spam signatures to maintain consistent, system-wide filtering effectiveness.
Data Flow: Typically, the connection over 2599 is initiated by the RA components querying the CC for updated filters and rules or submitting telemetry and analysis results. The Control Center aggregates this data, refines detection capabilities, and distributes updates accordingly.
Deployment: This communication is usually confined within internal or VPN-based networks of organizations leveraging SonicWALL's appliance and software. While the protocol specifics are proprietary, TCP ensures reliable delivery of analysis and control data, integral to maintaining the accuracy and responsiveness of antispam measures.
