With SpamAssassin (through amavisd-new or through spamc/spamd) there comes
a support for signature verification, for scoring and for whitelisting
based on SPF, DomainKeys and DKIM checks.
For DKIM signing one can use a dkim-milter or
Jason Long's dkimproxy ( http://jason.long.name/dkimproxy/ ).
For DomainKeys signing one can only use a dk-milter;
(the dkfilter proxy also exists, but uses an old Mail::DomainKeys
which is not recommended - loads entire mail in memory, and is
no longer actively maintained).
