- Flexible configurations to support multiple needs: gateway routing, HA clustering, disaster recovery, internal routing, and more
- Security and robustness from community development process and contributions to the open source MTA
Sentrion Policy Engine
The Sentrion Policy Engine provides award winning enterprise email security delivering centralized policy management over inbound and outbound mail to eliminate unwanted messages, defend network assets, protect private and confidential data, and enable compliance. With the Sentrion Policy Engine, IT messaging personnel can create policies based on any centrally defined action; on any message; with any condition; from any individual sender, group, or division and to any recipient.

Sentrion Connection Controls
Sentrion Connection Controls provides complete control over inbound and outbound email traffic by throttling trusted email or dropping abusive traffic. It collects broad statistics about the behavior of individual senders, sender reputation, sending hosts, and network address blocks and enforces pre-defined limits. Based on the behavior or reputation of the connection, a range of actions are possible: permanently or temporarily reject; rate limit or throttle; or suspend. This scalable traffic shaping mechanism defends against a variety of attacks and unwanted email, as well as helps to smooth the flow of legitimate traffic.
- Proven to eliminate unwanted mail by a minimum of 50%, and with IP reputation application, up to 80% or more
- Prevents Denial of Service, Distributed Denial of Service, and Directory Harvest Attacks
- Rejects or throttles connections from hosts that are exceeding session limits, invalid recipient counts, or other parameters which may indicate an attack
- Shape traffic for all connections to manage quality of service and to ensure smooth traffic flow and network load
The Sentrion Directory is an LDAP directory that interfaces with existing directories and centralizes users, alternate email addresses, groups, mail distribution lists, administrative groups and policy-related information into a secure and centrally managed data repository. It provides this information to email servers across the enterprise to add intelligence to gateway security, routing, and policy enforcement.
- Works with Sentrion Connection Controls to block connections from servers attempting to send mail to invalid addresses
- Enables more intelligent policy-driven email processing
- Consolidates routing information from multiple groupware applications
- Provides accurate and intelligent routing of messages to recipients and mailstores
The Sentrion Quarantine is a flexible server-based and/or per-use quarantine for disposing suspect messagesinbound spam at the gateway, outbound messages suspected of policy violations, and more.
- Quarantine Server: designates the role of the Sentrion as strictly a quarantine-only host containing a quarantine mailstore.
- Per-User Filtering Gateway: A quarantine mailstore for per-user filtering rules
- Works hand-in-hand with the Sentrion Platform Directory component.
