After using SpamAssassin for quite a while, it just wasn't cutting it - 75%-80% accuracy is still a lot of spam to go through and delete. I added DSpam to my mail server and my spam catching rate is now better than 99%.
DSpam also came with much better directions for integrating with Exim than did SpamAssassin. As fond as I was of SpamAssassin, they have some catching up to do.
The best feature of DSPAM, in my opinion, is that the SPAM never leaves the mail server.
The bad messages go into a quarantine on the server and can be reviewed by the end user using a web-based interface (looking for false positives.) In the press of a button, that quarantine can be emptied, freeing up disk resources on the server.
Other SPAM solutions (like SpamAssassin) mark the message and continue with delivery. What's the point in downloading the SPAM to your mail client just to throw them away?
