DKIM validation require access to full message body. For performance reasons amavisd-new present only $sa_mail_body_size_limit to spamassassin.
maybe this is why amavisd have mail::dkim support so its not needed to let mail::spamassassin::plugins::dkim do dkim verify with limited body size, i have just not seen a config to reuse amavisd results on dkim in spamassassin
again problem is that amavisd should not limit content scanning that is lover then mta ehlo size
all else will fail
