Basic Granularity Test of SPF/SIDF Results
To get a basic measure of the SPF/SIDF verification results for incoming mail,
you can use content filters and the Email Security Monitor - Content Filters page.
This test provides a view of the number of messages received for each type of
SPF/SIDF verification result.

To perform a basic SPF/SIDF verification test:
Step 1
Enable SPF/SIDF verification for a mail flow policy on an incoming listener, and
use a content filter to configure an action to take. For information on enabling
SPF/SIDF, see

Step 2
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

Step 3
After you have processed 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.

Greater Granularity Test of SPF/SIDF Results
For more comprehensive information about SPF/SIDF verification results, only
enable SPF/SIDF verification for specific groups of senders, and review the
results for those specific senders. Then, create a mail policy for that particular
group and enable SPF/SIDF verification on the mail policy. Create content filters
and review the Content Filters report as explained in
