NSE7 Advanced Threat Protection Practice Question
A company uses FortiMail for email security. They want to prevent email spoofing by verifying that incoming emails originate from authorized servers. Which email authentication method should be configured on FortiMail to check the sending server's IP against a published SPF record?
⚠ Common exam trap
Many candidates confuse SPF verification with DKIM or DMARC, thinking that any of these methods directly check the sending server's IP, when only SPF performs that specific IP-to-record lookup.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
SPF verification
SPF (Sender Policy Framework) verification on FortiMail checks the sending server's IP address against the SPF record published in the domain's DNS. This directly matches the requirement to verify that incoming emails originate from authorized servers, as SPF is designed to prevent spoofing by validating the envelope sender's domain against a list of permitted IPs.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
SPF verification
Why this is correct
SPF checks if the sending IP is authorized by the domain's SPF record.
- ✗
DKIM verification
Why it's wrong here
DKIM uses digital signatures, not SPF records.
- ✗
DMARC verification
Why it's wrong here
DMARC uses SPF and DKIM results, but the check itself is done by SPF.
- ✗
Sender Policy Framework (SPF) is not supported on FortiMail
Why it's wrong here
FortiMail fully supports SPF.
