Botnet Analysis

If botnet analysis is enabled, DNS validation is performed on the first untrusted relay looking for signs of a potential botnet infected host. For example, no reverse DNS, a hostname that would indicate an ISP client or other hosts that aren't intended to be acting as a direct mail submitter outside of their own domain.

Go to Anti-Spam Engine > Settings > Botnet Analysis to enable or disable botnet analysis.
