I don't know about dspam, I'm using SpamAssassin *globally* in a
before-queue content filter. Yes, it rejects the entire message for all
recipients, but that's the point. My users don't even know their mail is
being filtered (and will complain about getting as many as 5-10 spam
messages in a week!). I use a lot of different spam-fighting techniques,
but *all* of them are apparent to the sender (rejections, no
backscatter), so I will hear about any problems that occur (rare, but it
does happen).

I used to quarantine everything, inspect it, then pass on the ham, but
that was a *true* administrative nightmare. This approach adds
complexity to configuration, and lets me enjoy my vacations a little
more. :)

Don't overlook Chris' point about scalability, which cuts both ways. I'm
not an ISP, and support most of my clients down to their desktops, so
eliminating spam and viruses can save me support calls down the line.
But in a large general purpose population, per-user spam categorization
may be mandatory.
