Cisco Cisco Email Security Appliance C170 사용자 가이드

The following example shows a user configuring the SPF/SIDF verification using 
the SPF Only conformance level. The appliance performs the HELO identity 
check and accepts the None and Neutral verification results and rejects the others. 
The CLI prompts for the SMTP actions are the same for all identity types. The 
user does not define the SMTP actions for the MAIL FROM identity. The 
appliance automatically accepts all verification results for the identity. The 
appliance uses the default reject code and text for all REJECT results.
