spamass-milter hooks into the beginning of the message receipt stage,
whereas procmail/spamc hooks into the very end of the delivery stage,
after sendmail has determined the recipient's name.  Try using the -u
flag when you launch spamass-milter.  This will make it pull the
recipient name from the envelope and pass it to spamc.  Note that since
the milter is called only once for each incoming message, an email
CC'ed to two local recipients will get miltered only once, with the
default settings.
