Not sure what products you used, but I have such a solution in place 
for myself and a couple of clients.
Running a Linux based firewall in front of the network/servers and on 
that box a mod/add-on for that firewall that adds SMTP filtering 
without a hitch, utilizing both ClamAV and DSpam and a few blacklists.
Easy to set up, and learned to catch +95% just within the first few 
hours. And all for just $0.00 (not counting a possible RAM upgrade 
for the firewall, as specially ClamAV is a memory hog, but that's 
still <$80 in most cases)...
