SPF (Sender Policy Framework) is a sender authentication method developed in order to ensure mail server's security by applying different anti-spoofing mechanisms. This mechanism consists in making a DNS request in order to determine whether the mail message comes from an authorized source, which is described in a SPF record, registered on the DNS.  SPF records contain domain attributes that uniquely describe mail messages.

The query may have one of the following seven possible results:

• pass: meaning the message meets the domain's definition for legitimate messages;
• neutral
• none
• soft fail
• fail: meaning the message does not meet the domain's definition for legitimate messages;
• temp error
• permanent error
  

In case of permanent error, AXIGEN rejects the mail message generating the respective error. If a temporary error is generated, the AXIGEN returns an error message to the sending party. In all other cases the mail message is accepted.

To enable SPF in AXIGEN or to add a SPF header to emails, use the Message Acceptance Rules.

DomainKeys Compliance
Starting with version 2.0, AXIGEN Mail Server is also DomainKeys compliant. DomainKeys is an e-mail authentication system designed to verify both the DNS domain of an email sender and the message integrity, ebedded in the AXIGEN Signing Module. The DomainKeys specification has adopted aspects of Identified Internet Mail to create an enhanced protocol called DomainKeys Identified Mail (DKIM).

The AXIGEN Signing Module is only available for the commercial versions of the AXIGEN Mail Server. It does not work within free of evaluation versions. To test this specific feature, please contact our sales department.
