DKIM library and milter implementation

OpenDKIM is an open source implementation of the DKIM Domain Keys Identified Mail sender authentication system proposed by the E-mail Signing Technology Group ESTG, now standardized by the IETF RFC4871. It also includes an implementations of the Vouch By Reference VBR, RFC5518 proposed standard.

The OpenDKIM package consists of a library that implements the DKIM service and a milter-based filter application that can plug in to any milter-aware MTA to provide that service to sufficiently recent sendmail MTAs and other MTAs that support the milter protocol.
