 The OpenDKIM Project is a community effort to develop and maintain a C library
 for producing DKIM-aware applications and an open source milter for providing
 DomainKeys Identified Mail (DKIM) service.
 .
 DKIM provides a way for senders to confirm their identity when sending email
 by adding a cryptographic signature to the headers of the message.
 .
 This package contains the OpenDKIM mail filter (Milter) for plugging into
 Milter-aware MTAs. It implements both signing and verification.
