OpenDMARCDMARC library and mail filter for email authentication.
DMARC library and mail filter for email authentication.
OpenDMARC adds DMARC policy enforcement and reporting to a mail server through the milter protocol. It combines authentication results with domain policies published in DNS to determine how messages should be handled. The package includes a DMARC parsing library, a mail filter, and database tools that aggregate transaction history into reports; upstream DKIM checking is required.
