Flow Control

Use SenderBase for Flow Control

Enable “look ups” to the SenderBase Reputation Service for this listener.

 

Group by Similarity of IP Addresses: (significant bits 0-32)

Requires “Use SenderBase” to be disabled.
Used to track and rate limit incoming mail on a per-IP address basis while managing entries in a listener’s Host Access Table (HAT) in large CIDR blocks.
You define a range of significant bits (from 0 to 32) by which to group similar IP addresses for the purposes of rate limiting,
while still maintaining an individual counter for each IP address within that range.
Requires “Use SenderBase” to be disabled.
For more information about HAT significant bits, see Configuring Routing and Delivery Features.
