The 

spf-passed

 rule shows the results of SPF verification as a Boolean value. The 

following example shows an 

spf-passed

 rule used to quarantine emails that are 

not marked as spf-passed:

quarantine-spf-unauthorized-mail:

    if (not spf-passed) {

        quarantine("Policy");

    }

Unlike the 

spf-status 

rule, the 

spf-passed

 rule reduces the SPF/SIDF 

verification values to a simple Boolean. The following verification results are 
treated as not passed in the 

spf-passed

 rule: None, Neutral, Softfail, TempError, 

PermError, and Fail. To perform actions on messages based on more granular 
results, use the 

spf-status

 rule. 

Test the results of SPF/SIDF verification and use these results to determine how 
to treat SPF/SIDF failures because different organizations implement SPF/SIDF 
in different ways. Use a combination of content filters, message filters, and the 
Email Security Monitor - Content Filters report to test the results of the SPF/SIDF 
verification.

Your degree of dependence on SPF/SIDF verification determines the level of 
granularity at which you test SPF/SIDF results.
