How Sendmail IP Reputation Works
- Sentrion Appliances, or Sendmail Flow Control, queries the IP Reputation Data Center with the IP address of the sender during an SMTP session
- The IP Reputation Data Center replies with a risk level classification for each sender
- Risk level classifications can be mapped to a defined Sentrion policy, e.g. block or throttle suspicious traffic
- Graded classes/ risk levels enable intelligent connection management decisions for grey traffic based on:
- Statistical analysis of averages over time and recent changes of:
- Mail volume
- Spam ratio
- Valid bulk ratio
- Real-time zombie/botnet detection
- Continuously refined composite RBL score
- Use of IP DNS and whois attributes such as:
- Domain age
- Geography
- Known dynamic IP
