Enable strong spam filters to prevent phishing e-mails from reaching the end users and authenticate in-bound e-mail using technologies like Sender Policy Framework (SPF), Domain Message Authentication Reporting and Conformance (DMARC), and DomainKeys Identified Mail (DKIM) to prevent e-mail spoofing.

Almost a decade after the industry last set out to solve the problem with DomainKeys Identified Mail (DKIM)and Microsoft's Sender Policy Framework(SPF, later called Sender ID), DMARC's arrival is an acceptance that these have not been enough.

Included in this release are default configurations for the recent Internet Engineering Task Force's (IETF) standard DomainKeys Identified Mail (DKIM) (RFC 4871) email authentication method, the first commercial implementation of Vouch By Reference (VBR) for a free message certification service to MDaemon users, and implementation of Backscatter Protection (BATV protocol) to minimize the annoyance of receiving non-delivery replies to messages that were never sent by a user.
