However, for a larger installation, bogofilter simply won't work well, because it doesn't support a multiuser database (like MySQL or PostgreSQL). dspam also provides several other categorization schemes which bogofilter doesn't have.
So one of the key differences is the lack of a database that you can query by user? bogofilter would probably just give each user their own wordlist or use one wordlist to join them all. But the pros/cons of that decision belong elsewhere.
I can personally confirm that dspam works great; my personal account stats are:
filtering accuracy is 98.895% since last reset false positive rate is 0.728% since last reset
I'm not sure what you mean by a reset.
Bogofilter and SA, when they added Bayesian filtering) both exhibited a rather retarded functionality for the first 100 emails or so. After a bit they began to learn. Given that initial curve... Unless dspam starts with a preloaded wordlist or something else, I can't imagine it's success being significantly different at the beginning.
After training a few thousand emails, I think they all start to approach 99.999%. But again, that's a different list.
But I'm to understand that dspam is still implimented as a maildrop/procmail add-in? Just like bogofilter and SpamAssassin (minus amavisd)?
