dkimsign - Script for DKIM signing messages on stdin
dkimsign is a filter that reads an RFC822 message on standard input, and writes
the same message on standard output with a DKIM-Signature line prepended.
The signing options are specified on the command line:
dkimsign selector domain privatekeyfile [identity]
The identity is optional and defaults to "@domain".
