Step 2
Create a sender group for SPF/SIDF verification and use a naming convention to 
indicate SPF/SIDF verification. For information about creating sender groups, see 
the “Configuring the Gateway to Receive Mail” chapter in the Cisco IronPort 
AsyncOS for Email Configuration Guide
.
Step 3
Create an 
spf-status
 content filter for each type of SPF/SIDF verification. Use 
a naming convention to indicate the type of verification. For example, use 
“SPF-Passed” for messages that pass SPF/SIDF verification, or “SPF-TempErr” 
for messages that weren’t passed due to a transient error during verification. For 
information about creating an 
spf-status
 content filter, see 
Step 4
After you process a number of SPF/SIDF-verified messages, click Monitor > 
Content Filters to see how many messages triggered each of the 
SPF/SIDF-verified content filters.
