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.
