Infrastructure teams managing high-volume mail servers should choose Rspamd for its lightweight filtering engine that doesn't degrade throughput the way heavier solutions do. The 2,396 GitHub stars and active open-source community signal solid production stability, and its modular architecture means you integrate exactly what you need into your MTA stack rather than replacing it. Skip this if your organization needs centralized policy management and reporting across multiple mail nodes; Rspamd is a filtering tool, not an enterprise email security platform.
Startups and SMBs overwhelmed by phishing and credential theft should consider MX Layer Email Security for its AI-powered filtering that catches polymorphic threats without the overhead of larger platforms. The platform covers the full NIST Detect and Respond spectrum, with continuous monitoring and adverse event analysis built in, which matters when your security team is understaffed. Skip this if you need deep integration with your existing SIEM or require advanced forensics; MX Layer's strength is speed of deployment and operational simplicity, not investigative depth.
