Besides clamsmtpd there is DspamPD http://caspian.dotconf.net/menu/Software/DspamPD/ and also ASSP http://assp.sourceforge.net/ Beware that using clamsmtpd/dspampd alone will probably make your mail server an open relay. The problem is that that the server will see all connections as coming from itself (in fact from 127.0.0.1) because these proxies are only semi-transparent. As you mention, this can be solved by using Linux's firewall settings and clamsmtpd has some documentation on how to do it.
