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.
