John, In the interest of checking out other possibilities with active development, take a look at the rspamd project[1], particularly for high-volume applications.
Search this lists archives for some postings from the developer and some discussion regarding rspamd/rmilter/spamassassin I'm using the "postfix+amavis+clamav+spamassassin" stack myself. Works well for my needs, no complaints or issues and have used it for years.
