Amavisd replacement suggestion

[tsmullins]

We have been running Spamassassin for two years or so now.  Spamassassin has been great.  We run Postfix, Amavisd and Spamassassin.  I really need some suggestions to replace Amavisd.  I have two problems with Amavisd that I cannot seem to fix.  Any recommendations on how to call Spamassassin would be welcome.   Thanks Shane
