Chapter 26      FIPS Management
  Managing Keys for DKIM Signing and Verification
FIPS-compliant signing keys are available for use in domain profiles and appear in the Signing Key list 
when creating or editing a domain profile using the Mail Policies > Domain Profiles page. Once you 
have associated a signing key with a domain profile, you can create DNS text record which contains your 
public key. You do this via the Generate link in the DNS Text Record column in the domain profile listing 
(or via 
domainkeysconfig -> profiles -> dnstxt
 in the CLI).
DKIM Verification
The appliance requires a message to use a FIPS-compliant key in order to verify a DKIM signature. If 
the signature does not use a FIPS-compliant key, the appliance returns a permanent failure.
