We are working on implementing DSPAM here, and so far it seems pretty nice.  
The other nice thing is that DSPAM can be configured to directly talk to 
clamd via a port, so there is no need to add another layer to the Postfix 
content filter stack.  Once you have DSPAM configured (albeit, it can be a 
bit daunting) and talking to Clamd, you add about ten lines to the postfix 
config, and the two of them are talking.  Really slick.
