Cisco Cisco Email Security Appliance C160 Références techniques

When configuring the default settings for a listener’s Host Access Table, you can 
choose the listener’s SPF/SIDF conformance level and the SMTP actions 
(ACCEPT or REJECT) that the appliance performs, based on the SPF/SIDF 
verification results. You can also define the SMTP response that the appliance 
sends when it rejects a message.

Depending on the conformance level, the appliance performs a check against the 
HELO identity, MAIL FROM identity, or PRA identity. You can specify whether 
the appliance proceeds with the session (ACCEPT) or terminates the session 
(REJECT) for each of the following SPF/SIDF verification results for each 
identity check:

None. No verification can be performed due to the lack of information. 

Neutral. The domain owner does not assert whether the client is authorized 
to use the given identity.

SoftFail. The domain owner believes the host is not authorized to use the 
given identity but is not willing to make a definitive statement. 

Fail. The client is not authorized to send mail with the given identity.
