Nah! ASSP (anti spam smtp proxy) is actually a great opensource anti-spam proxy tool that (as it tunrs out) runs under Linux, FreeBSD and Windows. It loads a specified number of bytes of a given mail then refuses the connection based on a bayesian determination of spam, RBL, etc. instead of downloading the whole thing (unless you want it to). It has RBL, whitelisting, greylisting, SPF, web-based interface, limited anti-virus (which I don't use), and its fast and reasonably simple to install. The only thing that would make it better (in my opinion) is if it were written in c/c++ instead of Perl. I like it quite a bit better than SpamAssassin myself.
At any rate, it appears I was wrong about the smtp authentication OR popb4 and it is actually popb4 AND smtp authentication, which is kool. So now I know. I will instruct my users to start using SMTP authentication because, as another use kindly pointed out recently, why not? Thanks again for your input, Davide!
