Like Eray Aslan wrote, start with:
  http://www.ijs.si/software/amavisd/amavisd-new-docs.html#dkim

If the intention is signing, then the signing filter should
preferably be positioned after a content filter, not before it,
e.g.
  postfix -> amavisd -> DKIM Proxy -> postfix

or:
  postfix -> amavisd -> postfix

Note that the use of dkfilter (based on Mail::DomainKays)
is not recommended. DomainKeys is now treated as a historical
document, all new uses should use DKIM. There are several
architectural (and implementational) problem with it,
e.g. treating of repeated header fields such as 'Received'.

Google has switched by now (earlier this year).


http://www.ijs.si/software/amavisd/amavisd-new-docs.html#dkim :
  On the other hand there exists a dkfilter SMTP-proxy by the same author,
  which calls a Perl module Mail::DomainKays, which in turn is not recommended
  because of its design limitation which requires loading the whole message
  into memory.


$ man Mail::DomainKeys

  NAME
       Mail::DomainKeys - A perl implementation of DomainKeys

  CAVEAT
       THIS MODULE IS OFFICIALLY UNSUPPORTED.

       Please move on to DKIM like a responsible Internet user.  I have.

       I will leave this module here on CPAN for a while, just in case someone
       has grown to depend on it.  It is apparent that DK will not be the way
       of the future. Thus, it is time to put this module to ground before it
       causes any further harm.

       Thanks for your support, Anthony


$ man Mail::SpamAssassin::Plugin::DomainKeys

       Note that if the "Mail::SpamAssassin::Plugin::DKIM" plugin is installed
       with "Mail::DKIM" version 0.20 or later, that plugin will also perform
       Domain Key lookups on DomainKey-Signature headers, in which case this
       plugin is redundant.

       Here is author's note from module "Mail::DomainKeys" version 1.0:

         THIS MODULE IS OFFICIALLY UNSUPPORTED.

         Please move on to DKIM like a responsible Internet user.  I have.


Mark
